TECHNICAL FIELD

This disclosure relates generally to crop harvesting, and relates more particularly to automated systems for selectively picking crops from plants.

BACKGROUND

Various crops, such as strawberries, have been harvested typically using manual labor due to the delicate nature of the crops and the selective nature of the harvesting. For example, laborers perform the harvesting by selectively picking ripe crops from the plants while leaving unripe crops on the plants for later harvesting when they have ripened. The high seasonal demand for laborers and the limited labor force has resulted in increased labor costs and crops being left unpicked. Further, labor shortages have resulted in portions of fields being left unplanted in order to avoid the effort, expense, and waste involved with growing unpicked crops.

In many embodiments, attachment mechanism 321 can be used to rotate picking apparatus 110 around central axis 311.

Turning ahead in the drawings, FIG. 4 illustrates a front view of gripper 312 in an open position. FIG. 5 illustrates a front view of gripper 312 in a closed position. Gripper 312 is merely exemplary, and embodiments of the gripper are not limited to embodiments presented herein. The gripper can be employed in many different embodiments or examples not specifically depicted or described herein. In many embodiments, each of the other grippers (e.g., 313-315 (FIG. 3 )) on picking apparatus 110 (FIG. 3 ) can be identical or similar to gripper 312. In several embodiments, gripper 312 can be adjustable between the open position, as shown in FIG. 4 , and the closed position, as shown in FIG. 5 . In a number of embodiments, gripper 312 can be configured in the open position (as shown in FIG. 4 ) to open around an individual crop, such as a single strawberry growing on a strawberry plant, or another suitable crop. In many embodiments, gripper 312 can be configured in the closed position (as shown in FIG. 5 ) to securely hold the individual crop, such as strawberry 535, when picking apparatus 110 (FIGS. 1-3 ) is moved and/or rotated around central axis 311 (FIG. 3 ).

In various embodiments, gripper 312 can include a first claw piece 410 and a second claw piece 420.

In many embodiments, first tip 413 and/or second tip 423 can be wedge-shaped and/or configured to be inserted between crops to separate an individual crop from proximate crops (e.g., a cluster of crops) in order to pick the individual crop without damaging the proximate crops. For example, if a crop to be picked is located between two other nearby crops, first tip 413 can be configured to be wedged between the crop to be picked and another one of the nearby crops, and second tip 423 can be configured to be wedged between the crop to be picked and the other one of the nearby crops, which can separate and/or isolate the individual crop to be picked from the nearby crops without damaging the nearby crops.

In some embodiments, first claw piece 410 can include a retention surface 518, and/or second claw piece 420 can include a retention surface 528. Retention surface 518 and/or retention surface 528 can be configured to securely hold the crop (e.g., strawberry 535) in gripper 312. In several embodiments, such as shown in FIGS. 5 , retention surface 518 and/or retention surface 528 can each include a concave surface, which can at least partially surround the crop (e.g., strawberry 535) to facilitate securely holding the crop.

In several embodiments, gripper 312 can be spring biased to be in the open position, as shown in FIG. 4 . In a number of embodiments, gripper 312 can include a displacement block 430, which can be coupled to spoke 317, and which can be configured to slide radially inward and outward along spoke 317. In several embodiments, displacement block 430 can include a pin 431, which can facilitate coupling displacement block 430 to spoke 317. In many embodiments, spoke 317 can include a compression spring 432, which can compress when displacement block 430 is adjusted outward along spoke 317 to adjust gripper 312 to the closed position, as shown in FIG. 5 , and which can be biased to press displacement block 430 inward along spoke 317 to adjust gripper 312 to the open position, as shown in FIG. 4 . In various embodiments, gripper 312 can include one or more spring guards, such as spring guard 433 and/or spring guard 434, which can cover and/or protect compression spring 432.

In many embodiments, a first claw piece 410 can include a first displacement mounting portion 416 and a spoke mounting portion 417, and/or second claw piece 420 can include a second displacement mounting portion 426 and a spoke mounting portion 427. In a number of embodiments, spoke mounting portion 417 and/or spoke mounting portion 427 can be hingedly coupled to spoke 317, such as at a hinge 419 and/or a hinge 429, respectively. In several embodiments, first displacement mounting portion 416 and/or second displacement mounting portion 426 can be linkedly attached to displacement block 430, such that adjusting the position of displacement block 430 can adjust first claw piece 410 and/or second claw piece 420 between the open position, as shown in FIG. 4 , and the closed position, as shown in FIG. 5 , such as by rotating first claw piece 410 around hinge 419 and/or rotating second claw piece 420 around hinge 429.

In many embodiments, gripper 312 can include a first strip 414, a first linkage piece 415, a second strip 424, and/or a second linkage piece 425. First strip 414 and/or second strip 424 can be coupled to displacement block 430. First linkage piece 415 can be hingedly coupled to first displacement mounting portion 416 at a hinge 418, and can be coupled, such as slidably coupled, to first strip 414. Second linkage piece 425 can be hingedly coupled to second displacement mounting portion 426 at a hinge 428, and can be coupled, such as slidably coupled, to second strip 424. In many embodiments, first strip 414 and/or second strip 424 can be made of a flexible and/or abrasive-resistant semi-rigid material, such as ultra-high-molecular-weight (UHMW) polyethylene (UHMWPE). As shown in FIGS. 4-5 , as displacement block 430 is adjusted radially outward on spoke 317, first strip 414 can push first claw piece 410 forward to rotate around hinge 419 to the closed position, and first linkage piece 415 can slide outwardly along first strip 414 away from displacement block 430 as the position of first displacement mounting portion 416 is adjusted. Similarly, as displacement block 430 is adjusted radially outward on spoke 317, second strip 424 can push second claw piece 420 forward to rotate around hinge 429 to the closed position, and second linkage piece 425 can slide outwardly along second strip 424 away from displacement block 430 as the position of second displacement mounting portion 426 is adjusted.

In several embodiments, as displacement block 430 is adjusted radially outward on spoke 317, first strip 414 and/or second strip 424 can bend backward (i.e., toward a center of frame 316 (FIG. 3 )) to account for first claw piece 410 and/or second claw piece 420, respectively, not fully pushing forward in their rotation around hinge 419 and/or hinge 429, respectively. For example, if gripper 312 is utilized to pick a large-size crop, the size of the crop can prevent first claw piece 410 and/or second claw piece 420 from being fully pushed forward in their rotation around hinge 419 and/or hinge 429, respectively. When displacement block 430 is adjusted radially outward on spoke 317, first strip 414 and/or second strip 424 can provide spring-loaded bias on first claw piece 410 and/or second claw piece 420, respectively, to securely hold a crop (e.g., strawberry 535) in gripper 312. In a number of embodiments, the spring-loaded bending of first strip 414 and/or second strip 424 can advantageously allow gripper 312 to pick crops of various different sizes and securely hold those different-sized crops without damaging the crops. For example, gripper 312 can be configured to pick strawberries ranging from small-sized strawberries to large-sized strawberries.

In a number of embodiments, actuator 661 can include guide portions 762, which can each fit horizontally between left actuator bearings 766 and right actuator bearings 767, respectively. For example, guide portions 762 can guide the vertical adjustment of actuator 661 between, and prevent the vertical movement beyond, the top bearings and bottom bearings of left bearings 766 and/or right bearings 767. In certain embodiments guide portions 762 can include attachment pieces 763, which can attach actuator 661 to attachment bases 765 on gear housing 652 (FIGS. 6, 8 ) of carriage 650 (FIGS. 6, 8 ) via springs (e.g., extension springs) or other suitable elastic components, in order to bias actuator 661 in a vertically upward position to engage with actuation cam 660.

Turning ahead in the drawings, FIG. 9 illustrates a top, rear, left side perspective view of actuation cam 660, actuator 661, and stationary cam 669. Actuation cam 660, actuator 661, and stationary cam 669 are merely exemplary, and embodiments of the actuation cam, actuator, and stationary cam are not limited to embodiments presented herein. The actuation cam, actuator, and stationary cam can be employed in many different embodiments or examples not specifically depicted or described herein. In many embodiments, actuator 661 can include a cam interface piece 960, which can follow the shape of actuation cam 660 to adjust the position of actuator 661. In several embodiments, actuation cam 660 can be attached to motor 653 (FIGS. 6-8 ) at rotation point 961, and actuation cam 660 can rotate around rotation point 961. In many embodiments, actuation cam 660 can rotate in a counter-clockwise direction, as viewed from the rear perspective shown FIG. 9 . As actuation cam 660 rotates, cam interface piece 960 can move along actuation cam 660 from a base point 962 of actuation cam 660 to a peak point 963 of actuation cam 660, which can push actuator 661 vertically downward. As actuation cam 660 rotates further, cam interface piece 960 can drop back from peak point 963 to base point 962.

In several embodiments, actuator 661 can include a gripper interface portion 969, which can interface with a gripper (e.g., 312-315 (FIG. 3 )) on picking apparatus 110 (FIGS. 1-3 ) to adjust the adjustment position of the gripper (e.g., 312-315 (FIG. 3 )) between the open position (as shown in FIG. 4 ) and the closed position (as shown in FIG. 5 ). The gradual, continuous increase of actuation cam 660 can beneficially allow motor 653 (FIGS. 6-8 ) to precisely control the vertical position of actuator 661, which can advantageously allow motor 653 to precisely control the adjustment position of the gripper (e.g., 312-315 (FIG. 3 )) on picking apparatus 110 (FIGS. 1-3 ). For example, motor 653, actuation cam 660, and actuator 661 can be used to precisely adjust the position of first tip 413 (FIGS. 4-5 ) of first claw piece 410 (FIGS. 4-5 ) and second tip 423 (FIGS. 4-5 ) of second claw piece 420 (FIGS. 4-5 ) in order to fit around an individual crop to be picked, and to separate and/or isolate the individual crop to be picked from the other nearby crops without damaging the nearby crops.

In a number of embodiments, stationary cam 669 can include a circular slot 968, which can be configured to surround rotational shaft 655 (FIGS. 6-7 ). In several embodiments, stationary cam 669 can have a fixed position with respect to carriage 650 (FIGS. 6, 8 ), and the grippers (e.g., 312-315 (FIG. 3 )) on picking apparatus 110 (FIGS. 1-3 ) can rotate around stationary cam 669. In many embodiments, the rotational path of stationary cam 669 can include a first portion 964. Stationary cam 669 can be configured to hold the grippers (e.g., 312-315 (FIG. 3 )) on picking apparatus 110 (FIGS. 1-3 ) in a closed position (as shown in FIG. 5 ) along first portion 964 of the rotational path. In several embodiments, the rotational path of stationary cam 669 can include a second portion 965. In a number of embodiments, second portion 965 of the rotational path can include a release position 967 and a picking position 966. Stationary cam 669 can be configured to allow the grippers (e.g., 312-315 (FIG. 3 )) on picking apparatus 110 (FIGS. 1-3 ) to open to the open position (as shown in FIG. 4 ) along second portion 965 of the rotational path from release position 967 to picking position 966.

Turning ahead in the drawings, FIG. 10 illustrates a rear view of actuation cam 660, actuator 661, stationary cam 669, and picking apparatus 110 with gripper 312 in picking position 966 being in the open position. FIG. 11 illustrates a rear, right side perspective view of actuation cam 660, actuator 661, stationary cam 669, and picking apparatus 110 with gripper 312 in picking position 966 being in the closed position. In a number of embodiments, gripper 312 can include a displacement pin 1032 and/or a bearing 1012. In a number of embodiments, displacement pin 1032 can be identical to or attached to pin 431 (FIGS. 4-5 ). In many embodiments, displacement pin 1032 can be coupled to displacement block 430 (FIGS. 4-5 ), such that adjusting displacement pin 1032 can adjust displacement block 430. In many embodiments, bearing 1012 can be centered on displacement pin 1032, and can rotate along the rotational path of stationary cam 669. Similarly, gripper 313 can include a displacement pin 1033 and/or a bearing 1013; gripper 314 can include a displacement pin 1034 and/or a bearing 1014; and/or gripper 315 can include a displacement pin 1035 and/or a bearing 1015. Displacement pin 1033, displacement pin 1034, and/or displacement pin 1035 can be similar or identical to displacement pin 1032. Bearing 1013, bearing 1014, and/or bearing 1015 can be similar or identical to bearing 1012.

In many embodiments, motor 654 (FIGS. 6-8 ) can rotate picking apparatus 110 in a counter-clockwise direction, as viewed from the rear perspective shown in FIGS. 10-11 . Gripper 312 can be rotated to picking position 966 of second portion 965 of the rotational path of the grippers (e.g., 312-315 (FIG. 3 )) along stationary cam 669. In many embodiments, stationary cam 669 can include a stopping edge 1066, which can stop bearing 1012 in the rotation of picking apparatus 110 to stop gripper 312 at picking position 966. In many embodiments, when gripper 312 is in picking position 966, gripper 312 can be facing downward to allow gripper 312 to pick a crop from a growing bed. When gripper 312 is rotated to picking position 966, actuation cam 660 can be rotated such that cam interface piece 960 of actuator 661 can be at base point 962 of actuation cam 660 and actuator 661 is adjusted upwards (e.g., retracted) with respect to stationary cam 669. When actuator 661 is in the retracted position, as shown in FIG. 10 , gripper interface portion 969 of actuator 661 can be at or proximate to second portion 965 of stationary cam 669, such that gripper 312 can remain in the open position.

In several embodiments, as gripper 312 rotates toward picking position 966, gripper 315 can rotate along the rotational path of stationary cam 669 from first portion 964 to second portion 965 at release position 967. In many embodiments, stationary cam 669 can include a release edge 1067, which can allow gripper 315 to gradually open from the closed position (as shown in FIG. 5 ) to the open position (as shown in FIG. 4 ) at release position 967. When gripper 315 is rotated to release position 967 and opens to the open position, gripper 315 can release a crop that it is holding, such as in a collection device. When gripper 312 is at picking position 966 and gripper 315 is at release position 967, grippers 313 and 314 can be positioned along first portion 964 of the rotational path of stationary cam 669, which can hold grippers 313 and 314 in the closed position, as shown in FIG. 10 . For example, grippers 313 and 314 can each be holding a crop.

In many embodiments, at picking position 966 and in the open position, as shown in FIG. 10 , gripper 312 can be ready to pick a crop from a plant. In several embodiments, carrier 170 (FIG. 1 ) can move carriage support assembly 140 such that gripper 312 is positioned over the crop to be picked. Motor 653 (FIGS. 6-8 ) can rotate actuation cam 660 to engage gripper interface portion 969 of actuator 661 with displacement pin 1032 of gripper 312 to adjust the position of first claw piece 410 (FIGS. 4-5 ) and second claw piece 420 (FIGS. 4-5 ) of gripper 312 in order to fit around the individual crop to be picked. For example, if the crop is a larger, such as a large-sized strawberry, gripper 312 can be set to a wider opening in the open position, and if the crop is smaller, such as a small-sized strawberry, gripper 312 can be set to a narrow opening in the open position, which can allow gripper 312 to separate and/or isolate the individual crop to be picked from the other nearby crops without damaging the nearby crops.

When gripper 312 is adjusted to the appropriate opening width for the crop to be picked, carriage support assembly 140 can lower carriage 150 such that first claw piece 410 (FIGS. 4-5 ) and second claw piece 420 (FIGS. 4-5 ) of gripper 312 can surround the crop to be picked. Motor 653 (FIGS. 6-8 ) can rotate actuation cam 660 such that cam interface piece 960 can move along actuation cam 660 to peak point 963, which can push extend actuator 661 to an extended position, as shown in FIG. 11 . As actuator 661 is extended, gripper interface portion 969 of actuator 661 can push displacement pin 1032 to adjust the position of gripper 312 to the closed position (as shown in FIG. 11 ). When gripper 312 is in the closed position, bearing 1012 of gripper 312 can be extended beyond stopping edge 1066 of stationary cam 669, such that gripper 312 can be rotated along first portion 964 of the rotational path of stationary cam 669. In many embodiments, gripper 312 can securely hold the picked crop as gripper 312 rotates along first portion 964. After gripper 312 picks the crop, motor 654 (FIGS. 6-8 ) can rotate picking apparatus 110 such that gripper 315 is rotated to picking position 966. Although picking apparatus 110 is shown with 4 grippers (e.g., 312-315), picking apparatus 110 can include fewer or additional grippers, and first portion 964 and second portion 965 of the rotational path of stationary cam 669 can be adjusted accordingly.

In various embodiments, control unit 1272 can be electrically coupled to processing unit 1273 and/or can include one or more controllers to control the motors in harvesting robot 100, such as motor 646 (FIGS. 6-8 ), motor 653 (FIGS. 6-8 ), motor 654 (FIG. 6-8 ), motor 1275 (FIGS. 12-13 ), and/or motor 1276 (FIGS. 12-13 ).

Turning ahead in the drawings, FIG. 14 illustrates a bottom, front, right side perspective view of a foliage displacement mechanism 1400. Foliage displacement mechanism 1400 is merely exemplary, and embodiments of the foliage displacement mechanism are not limited to embodiments presented herein. The foliage displacement mechanism can be employed in many different embodiments or examples not specifically depicted or described herein. In many embodiments, foliage displacement mechanism 1400 can be configured to move foliage of a plant to expose at least a portion of the crops under the foliage, which can allow imaging sensors 1290 (FIGS. 12-13 ) and/or 1291 (FIGS. 12-13 ) to detect the crops and/or allow the grippers (e.g., 312-315 (FIGS. 3, 10-11 )) of picking apparatus 110 (FIGS. 1-3 ) to pick the crops.

In several embodiments, foliage displacement mechanism 1400 can include a back surface 1410. In many embodiments, back surface 1410 can have a planar rectangular shape. In a number of embodiments, back surface 1410 can be configured to extend normal to a growing bed of the plant, as shown in FIG. 15 and described below. In several embodiments, foliage displacement mechanism 1400 can include a base 1420. Base 1420 can be configured to extend parallel to the growing bed of the plant from a back edge 1411 at back surface 1410 toward the center of the plant, as shown in FIG. 15 and described below. In a number of embodiments, base 1420 can have a semicircular shape.

In several embodiments, foliage displacement mechanism 1400 can include a surface 1440. Surface 1440 can extend from base 1420 upward to back surface 1410. In a number of embodiments, at least one or more portions of surface 1440 can be curved and/or have a concave shape. In some embodiments, at least one or more portions of surface 1440 can be shaped as at least a portion of an ellipse. In several embodiments, foliage displacement mechanism 1400 can include a channel 1450. In many embodiments, channel 1450 can extend from base 1420 at a bottom channel portion 1451 upwards through surface 1440 to a top channel portion 1452. In some embodiments, base 1420 can extend outward toward the plant from a left side of back surface 1410 to a left front portion 1421 and from a right side of back surface 1410 to a right front portion 1422. In many embodiments, base 1420 can recede back toward back surface 1410 in the center of base 1420 between left front portion 1421 and right front portion 1422 to bottom channel portion 1451.

In a number of embodiments, foliage displacement mechanism 1400 can include attachment mechanisms 1430 and/or 1431. Attachment mechanisms 1430 and 1431 can be configured to attach foliage displacement mechanism 1400 to foliage displacement base 1281 (FIGS. 12-13 ) at attachment portions 1383 (FIG. 13 ) and/or 1282 (FIGS. 12-13 ), respectively. Motor 1276 can be configured to adjust the position of foliage displacement mechanism 1400 to move foliage displacement mechanism 1400 toward or away from the plant. In many embodiments, as foliage displacement mechanism 1400 is moved toward the plant, foliage displacement mechanism 1400 can be positioned such that the channel 1450 surrounds the center of the plant. In a number of embodiments, foliage displacement mechanism 1400 can be configured, when moved toward the plant, to move the foliage upward and toward the center of the plant. For example, the curves on surface 1440 can be configured to lift the foliage upwards and towards the center of the plant, which can advantageously prevent damaging and/or tangling the foliage (such as the leaves, vines, and/or blossoms) of the plant.

Turning ahead in the drawings, FIG. 15 illustrates a right side view of harvesting robot 100 and foliage displacement mechanism 1400 hovering above a plant 1510 and growing bed 1501, with foliage displacement mechanism 1400 in a retracted position. To assist with water run-off, growing bed 1501 can be slightly angled. In other examples, growing bed can be flat. Plant 1510 can be a strawberry plant, as shown in FIG. 15 . In other examples, plant 1510 can be a tomato plant, a pepper (e.g., bell peppers, chili peppers, etc.) plant, an orange tree, or another suitable plant. As shown in FIG. 15 , plant 1510 can have a center 1513 (e.g., a crown of a strawberry plant), and foliage 1512, such as leaves, vines, and/or blossoms, that grow above growing bed 1501. Plant 1510 can have crops 1511 that, when ripe, are located on growing bed 1501. At least some of crops 1511 can be covered by foliage 1512.

In many embodiments, such as shown in FIG. 15 , harvesting robot 100 can be mounted and/or supported such that central axis 311 of picking apparatus 110 is parallel to growing bed 1501. In several embodiments, foliage displacement mechanism 1400 can be attached to carrier mechanism 170 at attachment portion 1282 and/or attachment portion 1383 (FIG. 13 ) on 1281 with one or more attachment poles, such as attachment pole 1520.

When a crop, such as one of crops 1511, is located to be picked, (a) mounting bearing 1274 can rotate carrier assembly 170 such that the gripper (e.g., 312-315 (FIG. 3 )) in picking position 966 (FIGS. 9-11 ) is radially in a line extending from center 1513 of plant 1510 through the crop (e.g., 1511) to be picked, (b) carrier assembly 170 can move carriage assembly 140 radially inward toward plant 1510, and (c) carriage assembly 140 can lower carriage 650 (FIGS. 6, 8 ) to lower picking apparatus 110 to allow a gripper (e.g., 312-315 (FIG. 3 )) to close and pick the crop (e.g., 1511). In some embodiments, the motion of harvesting robot 100 can beneficially conserve motion, and/or can do a minimum amount of movement, such as to harvest an average maximum number of crops (e.g., 1511) from plant 1510 in one rotation. For example, in some embodiments, harvesting robot 100 can be configured to harvest three crops from plant 1510. In other embodiments, harvesting robot 100 can be configured to harvest fewer or additional crops from plant 1510. In a number of embodiments, the picked crops can be deposited in a collection device as harvesting robot 100 moves to another plant.

Turning ahead in the drawings, FIG. 16 illustrates a top, rear view of foliage displacement mechanism 1400 hovering above plant 1510 in an extended position. In many embodiments, when foliage displacement mechanism 1400 is extended toward plant 1510, moving foliage 1512 (FIG. 15 ), imaging sensors 1290 and/or 1291 (FIGS. 12-13 ) can detect crops 1511 on growing bed 1501, and processing unit 1273 (FIGS. 12-13 ) can determine the crops to be harvested, such as based on ripeness. In many embodiments, harvesting robot 100 (FIGS. 1-2, 13, 15 ) can rotate around plant 1510 with foliage displacement mechanism 1400 in the extended position, as shown in FIG. 16 , in order for processing unit 1273 (FIGS. 12-13 ) to determine which of the crops (e.g., 1511) are the best crops to be picked.

In several embodiments, carriage 2045 can include a rotational shaft 2146 (FIG. 21 ), which can be configured to couple to picking apparatus 2010, and which can be driven by a motor in carriage 2045 (which can be similar or identical to motor 654 (FIGS. 6-8 ) to rotate picking apparatus 2010. In many embodiments, carriage support assembly 2041 can control a vertical position of carriage 2045, similarly as shown in carriage assembly 140 (FIGS. 1-2, 6-8, 13, 15 ) and described above, which can raise and/or lower picking apparatus 2010. For example, carriage 2045 and picking apparatus 2010 can be adjusted in a lowered position, as shown in FIG. 20 . Similarly, carriage 2045 and picking apparatus 2010 can be adjusted to a raised position, as shown in FIG. 21 .

In many embodiments, carriage support assembly 2041 can include a bottom base 2042. Bottom base 2042 can be similar or identical to bottom base 642 (FIGS. 6-8 ). In several embodiments, carriage support assembly 2041 can include a stem separation bar 2043, which can be attached to bottom base 2042. In a number of embodiments, stem separation bar 2043 can be configured to provide tension on a stem of an individual crop, such as one of crops 1511 (FIG. 20 ), when a gripper (e.g., gripper 2012) picks the crop (e.g., 1511 (FIG. 20 )) from plant 1510 (FIG. 20 ). For example, in many embodiments, a crop (e.g., 1511 (FIG. 20 )) can be separated from a stem (e.g., stem 2019 (FIG. 20 )) of the crop that holds the crop (e.g., 1511 (FIG. 20 )) to the plant (e.g., plant 1510 (FIG. 20 )) by holding a portion of the stem down with stem separation bar 2043 while pulling upward on the crop (e.g., 1511 (FIG. 20 )), which can provide a substantially perpendicular tension force to the stem (e.g., stem 2019 (FIG. 20 )) of the crop from the attachment of the stem (e.g., stem 2019 (FIG. 20 )) on the crop. In a number of embodiments, the crop can be raised upward by the gripper (e.g., gripper 2012) after it is picked, and the stem (e.g., stem 2019 (FIG. 20 )) can extend downward to stem separation bar 2043, which can apply tension and result in the efficient separation of the stem (e.g., stem 2019 (FIG. 20 )) from the crop (e.g., 1511 (FIG. 20 )). In many embodiments, the gripper (e.g., 2012) picking the crop (e.g., 1511 (FIG. 20 )) can be lowered through stem separation bar 2043, as shown in FIG. 20 . Stem separation bar 2043 can be stationary with respect to carriage support assembly 2041, and can remain in place when carriage 2045, picking apparatus 2010, and the grippers (e.g., gripper 2012) are lowered to pick the crop (e.g., 1511 (FIG. 20 )), as shown in FIG. 20 . After the gripper (e.g., 2012) closes around a crop (e.g., 1511 (FIG. 20 )), carriage 2045, picking apparatus 2010, and the grippers (e.g., gripper 2012) can be raised, as shown in FIG. 21 . Because stem separation bar 2043 remains stationary when the gripper (e.g., 2012) is raised, stem separation bar 2043 tension can apply tension to the stem (e.g., stem 2019 (FIG. 20 )) and snap the stem (e.g., stem 2019 (FIG. 20 )) from the berry. In many embodiments, stem separation bar 2043 and/or bottom base 2042 can encircle the stem (e.g., stem 2019 (FIG. 20 )) of the crop (e.g., 1511 (FIG. 20 )) that is picked, such that stem separation bar 2043 will apply tension to the stem (e.g., stem 2019 (FIG. 20 )) as the crop (e.g., 1511 (FIG. 20 )) is raised and/or rotated in the gripper (e.g., 2012).

In many embodiments, carrier assembly 2070 can include a mounting bearing 2074 (FIG. 20 ). Mounting bearing 2074 (FIG. 20 ) can be similar or identical to mounting bearing 1274 (FIG. 12 ).

Electronics unit 2071 can be similar to electronics unit 1271 (FIG. 12 ), and various components of electronics unit 2071 can be similar or identical to various components of electronics unit 1271 (FIG. 12 ). In many embodiments, electronics unit 2071 can include a control unit 2072 and/or a processing unit 2173 (FIG. 21 ). Control unit 2072 can be similar or identical to control unit 1272 (FIG. 12 ), and processing unit 2173 can be similar or identical to processing unit 1273 (FIG. 12 ). For example, control unit 2072 can be a suitable programmable logic controller (PLC), which can control motors in harvesting robot 2000. In several embodiments, processing unit 2173 can be similar to an embodiment of computer system 1700 (FIG. 17 ), which can include one or more processors configured to receive information from imaging sensors 2190 and/or 2191 to determine the location of the crops to be harvested. For example, processing unit can be configured to determine that certain crops are ripe and ready to be harvested, and other crops are not yet ripe or are damaged, and should not be harvested.

In several embodiments, carriage assembly 2040 and/or carrier assembly 2070 can include a collection apparatus 2001. In many embodiments, after a gripper (e.g., gripper 2012) has picking a crop (e.g., 1511 (FIG. 20 )) from a picking position, the gripper (e.g., gripper 2012) can be rotated while holding the crop (e.g., 1511 (FIG. 20 ), which can allow another gripper to pick another crop. In many embodiments, once the gripper (e.g., gripper 2012) has been rotated to an offload position, where the crop (e.g., 1511 (FIG. 20 )) can be offloaded from the gripper (e.g., gripper 2012) into collection apparatus 2001. In many embodiments, collection apparatus 2001 can hold crops that have been offloaded from the grippers (e.g., gripper 2012). In many embodiments, collection apparatus 2001 can include a gate 2002 (FIG. 20 ), which can open to allow collection apparatus 2001 to be emptied, such as when collection apparatus is full or when harvesting robot 2000 is positioned such that collection apparatus can empty into a suitable collection container or collection conveyer, such as when harvesting robot 2000 has finished rotating around plant 1510 (FIG. 20 ) and returned to its starting position. In many embodiments, gate 2002 (FIG. 20 ) can be opened using an actuator 2003.

In several embodiments, carriage assembly 2040 and/or carrier assembly 2070 can include a crop ejector 2004 (FIG. 20 ), which can facilitate moving a crop (e.g., 1511 (FIG. 20 )) from a gripper (e.g., 2012) in the offload position to collection apparatus 2001. In many embodiments, crop ejector 2004 can include an ejection plate 2005 (FIG. 20 ) and an actuator 2006 (FIG. 20 ). In a number of embodiments, ejection plate 2005 can prevent the crop (e.g., 1511 (FIG. 20 )) from falling out of the gripper (e.g., 2012) when the gripper opens to offload the crop (e.g., 1511 (FIG. 20 )). In several embodiments, ejection plate 2005 can push the crop out of the gripper (e.g., 2012) toward collection plate 2001 when the gripper (e.g., 2012) is in the open position. In many embodiments, actuator 2006 can move ejection plate 2005.

In many embodiments, the grippers (e.g., 2011-2015, 2116) of picking apparatus 2010 can be spring biased in a closed configuration. For example, gripper 312 shown in FIG. 4 , can be modified such that compression spring 432 (FIG. 4 ) can be situated on the other side of pin 431 to bias displacement block 430 outward along spoke 317 to adjust gripper 312 to the closed position, such as the closed position of gripper 312 in FIG. 5 . In yet another embodiment, compression spring 432 can be situated in the same position shown in FIG. 4 , but can be replaced with an extension spring, which can similarly bias displacement block 430 outward along spoke 317 to adjust gripper 312 to the closed position. In many embodiments, each of the grippers (e.g., 2011-2015, 2116) of picking apparatus 2010 can include a claw cushion, such as claw cushion 2317 shown on gripper 2012 in FIG. 23 , or claw cushion 2718 shown on gripper 2015 in FIG. 27 . In many embodiments, the claw cushion (e.g., 2317 (FIG. 23 ), 2718 (FIG. 27 )) can provide a surface on the inside of the gripper (e.g., 2011-2015, 2116) to prevent a picked crop in the gripper (e.g., 2011-2015, 2116) from being displaced from between the claw pieces (e.g., 410, 420 (FIG. 4 )) and falling into a hinge region proximate to the hinges (e.g., 419, 429 (FIG. 4 )). For example, when gripper 2015 opens in the offload position in FIG. 27 , crop cushion 2718 can prevent a crop within gripper 2015 from falling into the hinges of gripper 2015.

In many embodiments, picking apparatus 2010 can move the grippers (e.g., 2011-2015, 2116) in a rotational path centered with respect to the central axis of picking apparatus 2010. In several embodiments, a picking position can be located at the bottom of the rotational path, such as the position of gripper 2012 shown in FIGS. 22-27 . In other embodiments, the picking position can be located at a different location of the rotational path, such as a side of the rotational path, or a top of the rotational path. In many embodiments, each of the grippers (e.g., 2011-2015, 2116) can be configured to be opened to an open position, such as the open position of gripper 312 in FIG. 4 , when the gripper (e.g., 2012) is located at the picking position, as shown in FIGS. 22-23 . In many embodiments, the gripper (e.g., 2012) located at the picking position can be opened to the open position to pick a crop.

In several embodiments, the gripper (e.g., 2012) located at the picking position can be opened to the open position before or while picking apparatus 2010 and the gripper (e.g., 2012) in the picking position is lowered to pick the crop. In many embodiments, the gripper (e.g., 2012) in the picking position can be opened using an actuator, such as actuator 2210. In many embodiments, actuator 2210 can be configured to engage with a pin of the gripper, such as pin 431 in FIG. 4 or displacement pin 1032 in FIG. 10 , described above, and move the pin to adjust the position of the claw pieces (e.g., 410, 420 (FIG. 4 )) of the gripper (e.g., 2012) and adjust the gripper (e.g., 2012) to the open position. In many embodiments, actuator 2210 can pull the pin inward along the spoke (e.g., pulling pin 413 inward along spoke 317 in FIG. 4 ) to open the gripper (e.g., 2012). In many embodiments, actuator 2210 can be configured to adjust the position of the claw pieces (e.g., 410, 420 in FIG. 4 ) in order to fit around the individual crop to be picked, as such described above in connection with actuator 661 in FIG. 10 .

In many embodiments, when picking apparatus 2010 is in the raised position, each of the grippers (e.g., 2011-2015, 2116) can be in the closed position, which can allow picking apparatus 2010 to be rotated with one or more crops in one or more of the grippers (e.g., 2011-2015, 2116).

In many embodiments, when picking apparatus 2010 is in the raised position, one of the grippers (e.g., gripper 2015) can be opened to the open position to offload a crop from the gripper (e.g., 2015), such as shown in FIGS. 26-27 . In a number of embodiments, an offload position can be located at the top of the rotational path, such as the position of gripper 2015 shown in FIGS. 22-27 . In other embodiments, the offload position can be located at a different location of the rotational path, such as a side of the rotational path, or a bottom of the rotational path. In many embodiments, each of the grippers (e.g., 2011-2015, 2116) can be configured to be opened to an open position, such as the open position of gripper 312 in FIG. 4 , when the gripper (e.g., 2015) is located at the offload position, as shown in FIGS. 26-27 . In many embodiments, the gripper (e.g., 2015) located at the offload position be opened to the open position to offload a crop from the gripper (e.g., 2015).

In many embodiments, the gripper (e.g., 2015) in the offload position can be opened using an actuator, such as actuator 2220. In many embodiments, actuator 2220 can be configured to engage with a pin of the gripper, such as pin 431 in FIG. 4 or displacement pin 1032 in FIG. 10 , described above, and move the pin to adjust the position of the claw pieces (e.g., 410, 420 (FIG. 4 )) of the gripper (e.g., 2015) and adjust the gripper (e.g., 2015) to the open position. In many embodiments, actuator 2220 can pull the pin inward along the spoke (e.g., pulling pin 413 inward along spoke 317 in FIG. 4 ) to open the gripper (e.g., 2015).

In a number of embodiments, once the gripper (e.g., 2015) in the offload position is open, crop ejector 2004 can eject the crop in the opened gripper (e.g., 2015) in the offload position into collection apparatus 2001. For example, actuator 2006 can move ejection plate 2005 toward collection plate 2001, as shown in FIG. 26 . In many embodiments, ejection plate 2005 can be configured to fit between the claw pieces (e.g., 410, 420 (FIG. 4 )) of the gripper (e.g., 2015) in the offload position when the gripper (e.g., 2015) is in the open position.

In several embodiments, each of the grippers (e.g., 2011-2015, 2116) can pick a different individual crop, and picking apparatus 2010 can be configured to offload (e.g., continuously offload) the crops while picking apparatus 2010 is picking the crops in the individual grippers (e.g., 2011-2015, 2116). For example, crops can be offloaded during a time in which crops are being picked. In some embodiments, a gripper (e.g., 2011-2015, 2116) can pick a first crop at a first time. Later, a gripper different from the gripper that picked the first crop can pick a second crop, after which a gripper different from the gripper that picked the second crop can pick a third crop. During the time between the second crop and the third crop being picked, the first crop can be offloaded from the gripper that picked the first crop. In some embodiments, the gripper that picked the first crop can pick the third crop. In other embodiments, the gripper that picks the third crop can be different than the gripper that picked the first crop. In many embodiments, the second crops can be held in the gripper that picked the second crop when the first crop is offloaded from the gripper that picked the second crop. In a number of embodiments, the second crop and the third crop can be held the grippers that picked them respectively when the third crop has been picked.

In many embodiments, using picking apparatus 2010, as shown in FIGS. 20-27 , gripper 2012 in the picking position can pick a crop and gripper 2015 in the offload position can offload a crop from gripper 2015. Picking apparatus 2010 can rotate such that gripper 2013 (of if rotated the other rotational direction, gripper 2011) can pick a crop while gripper 2012 holds the crop until it is rotated to the offload position. Picking apparatus 2010, in the embodiment shown in FIGS. 20-27 , can hold up to four individual crops at a time when gripper 2012 has just picked a crop and gripper 2015 has not offloaded the crop, as gripper 2013 and gripper 2014 can also be holding crops. Gripper 2116 and gripper 2011 can be empty. In other embodiments, a crop in the gripper (e.g., 2015) in the offload position can be offloaded before the gripper (e.g., 2012) in the picking position is used to pick a crop, in which case picking apparatus can hold up to three crops. In several embodiments, a series of picks and offloads can be interleaved, with a pick followed by an offload, followed by a pick, followed by an offload, etc. In several embodiments, during this entire series of picks and offloads, picking apparatus can be holding at least one crop. In other embodiments, picking apparatus can be holding at least two crop, three crops, four crops, or another suitable number of crops each in individual grippers. In still other embodiments, a crop in the gripper (e.g., 2015) in the offload position can be offloaded simultaneously with the gripper (e.g., 2012) in the picking position picking a crop. In such embodiments, the gripper can be considered to have offloaded the first crop during the time period between the second crop and the third crop being picked, as described above. In yet other embodiments, picking apparatus 2010 can include a different number of grippers, as described above. For example, picking apparatus can include two grippers, and a pick in one of the two grippers can be followed by an offload in the other gripper, after which the other gripper can pick another individual crop.

In many embodiments, the continuous offload of crops from the grippers (e.g., 2011-2015, 2116) of picking apparatus 2010 can beneficially allow harvesting robot 2000 to pick many crops while rotating around a plant. For example, if a plant has seven ripe crops that are ready to be picked, harvesting robot 2000 can circle the plant, and pick the seven plants while simultaneously offload at least some of the crops while circling the plant and picking the seven crops. The offloaded crops can advantageously be collected in collection apparatus 2001.

Turning ahead in the drawings, FIG. 28 illustrates a perspective view of a leaf displacement system 2800 hovering over plant 1501 in an open configuration. FIG. 29 illustrates a perspective view of leaf displacement system 2800 hovering over plant 1501 and beginning to transition from the open configuration to a closed configuration. FIG. 30 illustrates a perspective view of leaf displacement system 2800 hovering over plant 1501 and further transitioning from the open configuration to the closed configuration. FIG. 31 illustrates a perspective view of leaf displacement system 2800 hovering over plant 1501 in the closed configuration. Leaf displacement system 2800 is merely exemplary, and embodiments of the harvesting robot are not limited to embodiments presented herein. The leaf displacement system can be employed in many different embodiments or examples not specifically depicted or described herein. Leaf displacement system 2800 can be similar to foliage displacement mechanism 1400 (FIG. 14 ), and leaf displacement system can be configured to move foliage of a plant, such as foliage 1512 of plant 1510, to expose at least a portion of the crops under the foliage, which can allow imaging sensors 1290-1291 (FIGS. 12-13 ) and/or images sensors 2190-2191 (FIG. 21 ) to detect the crops and/or allow the grippers (e.g., 312-315 (FIGS. 3, 10-11 ), 2011-2015 (FIGS. 20-21 ), 2116 (FIG. 21 )) to pick the crops, such as crops 1511.

In a number of embodiments, leaf displacement system 2800 can include a support structure 2810, a first assembly 2850, and/or a second assembly 2870. In many embodiments, first assembly 2850 and second assembly 2870 can each be movably coupled to support structure 2810, as shown in FIGS. 28-31 . In other embodiments, one of first assembly 2850 and second assembly 2870 can be movably coupled to support structure 2810 and the other one of first assembly 2850 and second assembly 2870 can be fixedly coupled to support structure 2810. For example, leaf displacement system 2800 can include a first assembly rail 2815 to movably couple first assembly 2850 to support structure 2810 and allow first assembly 2850 to extend from and/or retract to support structure 2810. Leaf displacement system 2800 can include a second assembly rail 2817 to movably couple second assembly 2870 to support structure 2810 and allow second assembly 2870 to extend from and/or retract to support structure 2810. In several embodiments, support structure 2810 can include one or more motors (not shown) to drive the extension/retraction of first assembly 2850 along second assembly rail 2815 and/or the extension/retraction of second assembly 2870 along second assembly rail 2817.

In some embodiments, leaf displacement system 2800 can include two or more surfaces, which can be movable with respect to each other, and can push and/or hold foliage 1512 toward center 1513 of plant 1510. In some embodiments, for example, each of the two or more surfaces can be curved or flat surfaces, which can push foliage 1512 toward center 1513. As shown in FIG. 28 , second assembly 2870 can include a second assembly base surface 2871, a second assembly first wing surface 2872, and a second assembly second wing surface 2873.

In many embodiments, second assembly base surface 2871 can be fixedly coupled to second assembly rail 2817, and second assembly first wing surface 2872 and second assembly second wing surface 2873 can each rotate with respect to second assembly base surface 2871. For example, in some embodiments, leaf displacement system 2800 can include arms 2821-2822 and gear 2831, with arm 2821 coupled to gear 2831 at one end of arm 2821 and coupled to arm 2822 at the other end of arm 2821, and arm 2822 coupled to arm 2821 at one end of arm 2822 and coupled to second assembly first wing surface 2872 at the other end of arm 2822, such that when gear 2831 rotates, second assembly first wing surface 2872 can be rotated. Similarly, leaf displacement system 2800 can include arms 2823-2824 and another gear (not shown), with arm 2823 coupled to the gear at one end of arm 2823 and coupled to arm 2824 at the other end of arm 2823, and arm 2824 coupled to arm 2823 at one end of arm 2824 and coupled to second assembly second wing surface 2873 at the other end of arm 2824, such that when the gear rotates, second assembly second wing surface 2873 can be rotated.

In some embodiments, leaf displacement system 2800 can rotate second assembly first wing surface 2872 and second assembly second wing surface 2873 when second assembly 2870 is extended and/or retracted along second assembly rail 2817. In many embodiments, as second assembly 2870 is retracted along second assembly rail 2817, second assembly base surface 2871, second assembly first wing surface 2872, and/or second assembly second wing surface 2873 can push foliage 1512 toward center 1513 of plant 1510.

As shown in FIG. 28 , first assembly 2850 can include a first assembly base surface 2851, a first assembly first wing surface 2852, and a first assembly second wing surface 2853. In many embodiments, first assembly base surface 2851 can be fixedly coupled to first assembly rail 2815, and first assembly first wing surface 2852 and first assembly second wing surface 2853 can each rotate with respect to first assembly base surface 2851. For example, in some embodiments, leaf displacement system 2800 can include arms 2851-2826 and gear 2832, with arm 2825 coupled to gear 2833 at one end of arm 2825 and coupled to arm 2826 at the other end of arm 2825, and arm 2826 coupled to arm 2825 at one end of arm 2826 and coupled to first assembly first wing surface 2852 at the other end of arm 2826, such that when gear 2833 rotates, first assembly first wing surface 2852 can be rotated. Similarly, leaf displacement system 2800 can include a first arm (not shown), an arm 2828 and another gear (not shown), with the first arm coupled to the gear at one end of the first arm and coupled to arm 2828 at the other end of the first arm, and arm 2828 coupled to the first arm at one end of arm 2828 and coupled to first assembly second wing surface 2853 at the other end of arm 2828, such that when the gear rotates, first assembly second wing surface 2853 can be rotated.

In some embodiments, leaf displacement system 2800 can rotate first assembly first wing surface 2852 and first assembly second wing surface 2853 when first assembly 2850 is extended and/or retracted along first assembly rail 2815. In a number of embodiments, second assembly 2850 can include a first assembly first plate surface 2854 and/or a first assembly second plate surface 2855. In many embodiments, first assembly first plate surface 2854 can be fixedly coupled to first assembly first wing surface 2852, such that first assembly first plate surface 2854 can rotate when first assembly first wing surface 2852 is rotated. In various embodiments, first assembly second plate surface 2855 can be fixedly coupled to first assembly second wing surface 2853, such that first assembly second plate surface 2855 can rotate when first assembly second wing surface 2853 is rotated.

In many embodiments, as first assembly 2850 is retracted along first assembly rail 2815, first assembly base surface 2851, first assembly first plate surface 2854, and/or first assembly second plate surface 2855 can push foliage 1512 toward center 1513 of plant 1510. In many embodiments, first assembly base surface 2851, first assembly first wing surface 2852, first assembly second wing surface 2853, second assembly base surface 2871, second assembly first wing surface 2872, and second assembly second wing surface 2873 can each be rounded surfaces, such as a portion of a cylinder. In many embodiments, when leaf displacement system 2800 is in the closed configuration, as shown in FIG. 28 , first assembly base surface 2851, first assembly first wing surface 2852, first assembly second wing surface 2853, second assembly base surface 2871, second assembly first wing surface 2872, and second assembly second wing surface 2873 can form a cylindrical shell that encloses first assembly first plate surface 2854, first assembly second plate surface 2855, and/or foliage 1512.

In several embodiments, second assembly first wing surface 2872 and second assembly second wing surface 2873 can each be larger than first assembly first wing surface 2852 and first assembly second wing surface 2853, to allow second assembly first wing surface 2872 and second assembly second wing surface 2873 to capture more of foliage 1512, as shown in FIG. 29 . Because first assembly first wing surface 2852 and first assembly second wing surface 2853 are smaller, and unable to capture as much of foliage 1512, first assembly first plate surface 2874 and first assembly second plate surface 2855 can be used by first assembly 2850 to capture more of foliage 1512, as shown in FIG. 29 . In many embodiments, first assembly first plate surface 2874 and first assembly second plate surface 2855 can capture foliage 1512 and sweep foliage 1512 within the cylindrical shell shown in FIG. 31 . As partially shown in FIG. 30 by first assembly first plate surface 2854, as first assembly first plate surface 2854 and first assembly second plate surface 2855 are rotated inward as leaf displacement system 2800 transitions from the open configuration (as shown in FIG. 28 ) to the closed configuration (as shown in FIG. 31 ), first assembly first plate surface 2854 and first assembly second plate surface 2855 can sweep within second assembly first wing surface 2872 and second assembly second wing surface 2873, such that when leaf displacement system 2800 is in the closed configuration, as shown in FIG. 30 , first assembly first plate surface 2854 and first assembly second plate surface 2855 can be fully enclosed within the cylindrical shell described above.

In many embodiments, foliage 1512 can be held within a circumference to expose crops 1511, and allow a harvesting robot (e.g., 100 (FIG. 1 ), 2000 (FIG. 20 )) to rotate around plant 1510 and detect and pick crops 1511 without interference from foliage 1512. In many embodiments, the circumference can be dictated by the type of plant being harvested. For example, in some plants, such as strawberry plants, the circumference can be no more than approximately 8 inches (20.32 centimeters (cm)), 7 inches (17.78 cm), 6 inches (15.24 cm), 5 inches (12.7 cm), or another suitable circumference. For other plants, the circumference can be another suitable circumference

In many embodiments, foliage displacement system 2800 can be carried such that a bottommost of foliage displacement system 2800, such as a bottommost part of first assembly base surface 2851, first assembly first wing surface 2852, first assembly second wing surface 2853, first assembly first plate surface 2874, first assembly second plate surface 2855, second assembly base surface 2871, second assembly first wing surface 2872, and/or second assembly second wing surface 2873 can be a first distance from growing bed 1501 when leaf displacement system 2800 transitions from the open configuration (shown in FIG. 28 ) to the closed configuration (shown in FIG. 31 ). In many embodiments, the distance can be dependent on the size of the crops (e.g., 1511) and/or the typical size of the foliage (e.g., 1512) when the crops are being harvested, such that the crops (e.g., 1511) are not captured by leaf displacement system 2800, but the foliage (e.g., 1512) is captured. For example, in some embodiments, such as when the crops are strawberries, the distance can be approximately 2 inches (5.08 cm) to 4 inches (10.16 cm). In other embodiments, the distance can be approximately 2.5 inches (6.35 cm) or approximately 3.0 inches (7.62 cm). In other embodiments, the distance can be another suitable distance.

In many embodiments, leaf displacement system 2800 can be held below carrier assembly 2070 (FIGS. 20-21 ) of harvesting robot 2000 (FIG. 20 ) or carrier assembly 170 (FIG. 1 ) of harvesting robot 100 (FIG. 1 ). For example, leaf displacement system 2800 can be held between mounting bearing 2074 (FIG. 20 ) and plant 1510 when mounting bearing 2074 is centered over plant 1510. In many embodiments, can be held stationary such that leaf displacement system 2800 does not rotate with respect to plant 1510 when harvesting robot 2000 (FIG. 20 ) or harvesting robot 100 (FIG. 1 ) rotates around plant 1510 to detect and pick crops, which can beneficially hold foliage 1512 in place without leaf displacement system 2800 damaging foliage 1512 or getting caught on foliage 1512.

In many embodiments, when the harvesting robot (e.g., 100 (FIG. 1 ), 2000 (FIG. 20 )) corresponding to leaf displacement system 2800 approaches plant 1510, such as a plant along a row of plants, leaf displacement system 2800 can be in the open configuration, as shown in FIG. 28 , and/or first assembly 2850 can be disposed on one side of plant 1510 and second assembly 2870 can be disposed on the opposite side of plant 1510, as shown in FIG. 28 , which can beneficially allow the harvesting robot (e.g., 100 (FIG. 1 ), 2000 (FIG. 20 )) and support structure 2810 of leaf displacement system 2800 to approach plant 1510 and become centered over plant 1510, after which leaf displacement system can transition from the open configuration to the closed configuration. After the harvesting robot (e.g., 100 (FIG. 1 ), 2000 (FIG. 20 )) has finished rotating around plant 1510 (and finished detecting and picking crops on plant 1510), leaf detection system 2800 can transition from the closed configuration (as shown in FIG. 31 ) to the open configuration (as shown in FIG. 28 ).

In other embodiments, a leaf displacement system can have other configurations. For example, a base surface can be surrounded by two wing surfaces, which can each rotate with respect to the base surface and can capture foliage 1512 within the base surface the two wing surfaces, to close in a triangular shape and hold foliage 1512.

Turning ahead in the drawings, FIG. 32 illustrates a top, rear, left side perspective view of a harvesting vehicle 3200 traveling through rows of plant beds 3280. FIG. 33 illustrates a rear view of harvesting vehicle 3200 traveling through rows of plant beds 3280. FIG. 34 illustrates a top view of harvesting vehicle 3200 traveling through rows of plant beds 3280. Harvesting vehicle 3200 is merely exemplary, and embodiments of the harvesting vehicle are not limited to embodiments presented herein. The harvesting vehicle can be employed in many different embodiments or examples not specifically depicted or described herein.

The rows of plant beds can include plant beds 3281-3290 which can be spaced apart to form rows 3291-3299. Plant beds 3281-3290 can include rows of plants, such as plants 3220. In some embodiments, plant beds 3280-3290 can be slightly angled, such as on each side of each of plant beds 3280-3290 to assist with water run-off In many embodiments, each angled side of the bed can include rows of plants. Plants 3220 can be a strawberry plant, a tomato plant, a pepper (e.g., bell peppers, chili peppers, etc.) plant, an orange tree, or another suitable plant.

In many embodiments, harvesting vehicle 3200 can be used to harvest plants 3220. In many embodiments, harvesting vehicle 3200 can include wheels, such as wheels 3201-3204 and a body 3210. In many embodiments, the wheels can roll along rows (e.g., 3291-3299) between the plant beds (e.g., 3281-3290). For example, in some embodiments, wheels 3201-3202 can roll along row 3292 and wheels 3203-3204 can roll along row 3298, such that harvesting vehicle 3200 straddles six plant beds (e.g., plant beds 3283-3288), and can be used to harvest four plant beds (e.g., plant beds 3284-3287) at a time. In other embodiments, harvesting vehicle 3200 can straddle more or fewer plant beds and can harvest more or fewer plant beds at a time. In the embodiment illustrated in FIG. 32 , rows 3291-3299 can be straight, but in a different embodiment, the rows can be curved.

In many embodiments, body 3210 can include frame pieces 3211-3212, which in some embodiments can be I-beams or other suitable frame pieces to provide support for body 3210 across the plant beds (e.g., 3283-3288) straddled by body 3210. In several embodiments, body 3210 can include arms 3213 and 3214 on each side of harvesting vehicle 3200, which can include global positioning system (GPS) receivers 3215 and 3216, respectively.

In a number of embodiments, body 3210 can include robot positioning carrier (RPC) tracks 3334-3337 (FIGS. 33-34 ). In many embodiments, RPC tracks 3334-3337 can carry robot positioning carriers (RPCs) 3240, 3250, 3260, and 3270, respectively. In many embodiments, each RPC can carry robots, such as harvesting robots 3461-3464 (FIG. 34 ), as explained in greater detail below. In several embodiments, body 3210 can include an RPC drive system 3230, which can control the position of RPCs 3240, 3250, 3260, and 3270 with respect to RPC tracks 3334-3337.

In many embodiments, RPC drive system 3230 can include an RPC motor 3231, an RPC drive block 3232, an RPC drive shaft 3233, and an RPC frame 3234. In a number of embodiments, RPC drive frame 3234 can be mounted to body 3210, such as to frame pieces 3211-3212. In several embodiments, RPC motor 3231 can be mounted to RPC drive frame 3234, and can drive RPC drive block 3232 to rotate RPC shaft 3233. In many embodiments, RPC shaft 3233 can extend through each of RPC tracks 3334-3337 to control the position of RPCs 324, 3250, 3260, and 3270 with respect to RPC tracks 3334-3337, as explained below in greater detail.

Turning ahead in the drawings, FIG. 35 illustrates a top, rear, right side perspective view of RPC 3260. FIG. 36 illustrates a bottom, front, right side view of RPC 3260 being carried by RPC track 3336 and showing a portion of RPC drive system 3230. FIG. 37 illustrates a rear view of a portion of RPC 3260 being carried by RPC track 3336 and showing a drive mechanism of RPC 3260 using RPC drive shaft 3233. RPC 3260 is merely exemplary, and embodiments of the RPC are not limited to embodiments presented herein. The RPC can be employed in many different embodiments or examples not specifically depicted or described herein. RPC drive system 3230 is merely exemplary, and embodiments of the RPC drive system are not limited to embodiments presented herein. The RPC drive system can be employed in many different embodiments or examples not specifically depicted or described herein.

In many embodiments, each RPC (e.g., 3240, 3250, 3260, 3270) can be the same as each other, such as RPC 3260. In many embodiments, RPC 3260 can carry harvesting robots 3461-3464, which can be similar or identical to harvesting robot 100 (FIG. 1 ) and/or harvesting robot 2000 (FIG. 20 ). In some embodiments, each harvesting robot (e.g., 3461-3464) can be include a mounting bearing, such as mounting bearings 3521-3524, respectively. Mounting bearings 3521-3524 can be similar or identical to mounting bearings 1274 (FIG. 12 ) and/or 2074 (FIG. 20 ). In many embodiments, RPC 3260 can include a carrier frame 3510, which can include mounting pieces 3511-3514, which can attach to mounting bearings 3521-3524, respectively. In many embodiments, mounting pieces 3511-3514 can be modular attachment pieces, which can be removably coupled to harvesting robots 3461-3464, respectively, such as to quickly replace a harvesting robot (e.g., 3461-3464) in case of malfunction, or to attach different types of robots, such as hole punching robots, as described below in further detail.

In several embodiments, RPC 3260 can carry four robots, as shown in FIGS. 35-36 . In other embodiments, RPC 3260 can carry another number of robots, such as 1, 2, 3, 5, 6, 7, 8, 9, 10, 11, 12, or another suitable number of robots. By carrying multiple robots, RPC 3260 can position multiple robots in place to each simultaneously perform tasks, such as harvesting plants or other suitable tasks. In many embodiments, RPC 3260 can position the robots such that the robots can perform the tasks simultaneously and independently without interfering with the other robots. For example, as shown in FIGS. 35-36 , RPC 3260 can space the robots two on each side, with interleaved spacing, as further shown in FIG. 39 and described below.

In many embodiments, for ease of service, each robot (e.g., 3461-3464) can have its own self-contained controller and processors, which can have communications and/or power connections to the rest of the harvesting vehicle (e.g., 3200 (FIGS. 32-34 )). Each one of these robots can include motor controls, position sensors, solenoid controls, cameras, vision processing, strobe controls, and/or other suitable components. The robots (e.g., 3461-3464) can act like a hive of bees that are orientated to perform certain tasks or functions when cued and report back when completed so that the higher-level system in the harvesting vehicle (e.g., 3200 (FIGS. 32-34 )) can perform next steps. In many embodiments, the robots (e.g., 3461-3464) can perform these basic functions simultaneously and independently when commanded. In case of the malfunction of one of the robots (e.g., 3461-3464), it is advantageous to be able to trade out the robot (e.g., 3461-3464) quickly so that the rest of the robots (e.g., 3461-3464) can continue working. A quick change-out system for the robots (e.g., 3461-3464) can be implemented by minimizing the electrical and mechanical connections it takes to replace a robot (e.g., 3461-3464). By including multiple RPCs (e.g., 3240, 3250, 3260, 3270 (FIGS. 32-34 )) each with multiple robots (e.g., 3461-3464) on harvesting vehicle 3200 (FIGS. 32-34 ), harvesting vehicle 3200 (FIGS. 32-34 ) can perform operations (e.g., picking, hole punching) on multiple rows during picking operations, increasing picking efficiency of harvesting vehicle 3200 (FIGS. 32-34 ). For example, harvesting vehicle 3200 (FIGS. 32-34 ) show in FIGS. 32-34 includes 16 different harvesting robots, which can pick crops on 16 different plants simultaneously. In other embodiments, harvesting vehicle 3200 (FIGS. 32-34 ) can include more or fewer harvesting robots and/or robots of a different type (e.g., hole punching robots or other suitable robots).

In many embodiments, carrier frame 3510 of RPC 3260 can include track coupling mechanisms 3515 and 3516, which can be configured to slidably couple to RPC track 3336. For example, track coupling mechanisms 3515-3516 can each include a number of wheels to couple RPC 3260 to RPC track 3336 and facilitate movement of RPC 3260 with respect to RPC track 3336, as shown in FIG. 36 .

In many embodiments, RPC drive shaft 3233 can extend through each RPC track, such as RPC track 3336, and can include two drums on each side of the RPC track, such as drums 3711 and 3712 (FIG. 37 ) on each side of RPC track 3336. In several embodiments, track 3336 can include a track wheel 3638 (FIGS. 36-37 ) at one end of RPC track 3336 and a track wheel 3739 (FIG. 37 ) at the other end of RPC track 3336. In some embodiments, track wheel 3638 can be of a one side of RPC track 3336, such as on the same side as drum 3711, and track wheel 3739 can be on the other side of RPC track 3336, such as drum 3712.

As shown in FIG. 37 , in several embodiments, a cable 3713 (FIG. 37 , not shown in other FIGs. for clarity) can be wrapped around drum 3711, extend from the front side of drum 3711 under drum 3711 and be wound around track wheel 3638, extend under RPC track 3336 to track wheel 3739, and be wound around track wheel 3739 to extend under and around drum 3712. In many embodiments, cable 3712 can be attached to RPC 3260 under RPC track 3336, such as on carrier frame 3510 (attachment not shown). In many embodiments, cable 3713 can create a positive engagement system, such that when RPC drive shaft 3233 rotates in a first rotational direction and rotates drums 3711-3712 in the first rotational direction, drum 3711 can further wind cable 3713 while drum 3712 unwinds cable 3713, which can result in cable 3713 moving RPC 3260 in a rearward direction. Similarly, when RPC drive shaft 3233 rotates in a second direction and rotates drums 3711-3712 in the second rotational direction, drum 3712 can further wind cable 3713 while drum 3711 unwinds cable 3713, which can result in cable 3713 moving RPC 3260 in a frontward direction. As shown in FIG. 36 , RPC motor 3231 can use RPC drive block to drive RPC drive shaft 3233 in either rotational direction.

In many embodiments, each RPC (e.g., 3240, 3250, 3260, 3270 (FIGS. 32-34 )) on harvesting vehicle 3200 can be driven by RPC drive shaft 3233, which is in common, and which can move and position each RPC (e.g., 3240, 3250, 3260, 3270 (FIGS. 32-34 )) together to the same position above the different plant beds (e.g., 3284-3287 (FIGS. 32-34 )).

Turning ahead in the drawings, FIG. 38 illustrates a set of time views 3811-3817 over time showing side views of a progression of an RPC 3803 on a track 3802 over a plant bed 3801. FIG. 39 illustrates a schematic of a portion of plant bed 3801, showing the position of robots carried by RPC 3803 over time. RPC 3803 can be similar or identical to RPCs 3240, 3250, 3260, or 3270 (FIG. 32-34 ). Track 3802 can be similar or identical to RPC tracks 3334-3337 (FIGS. 33-34 ). In many embodiments, RPC 3802 can carry robots 3804-3807, which can each by similar or identical to harvesting robot 100 (FIG. 1 ) or harvesting robot 2000 (FIG. 1 ), or another suitable robot. For example, robots 3804-3807 can be hole punching robots. Time views 3811-3817 can proceed sequentially, showing the progression of RPC 3803 and track 3802 over plant bed 3801.

Plant bed can include a plant row 3901 (FIG. 39 ) and a plant row 3902 (FIG. 39 ), which can each be a straight or curved row of plants. For example, plant row 3901 can include plants 3881-3895 and plant row 3902 can include plants 3821-3835. In some embodiments, robots 3804-3807 can pick plants 3881-3895 and 3821-3835, based on the pattern legend shown in FIG. 39 , and as described below in further detail.

In many embodiments, track 3802 can be attached to a vehicle, such as harvesting vehicle 3200 (FIGS. 32-34 ), or another suitable vehicle. In many embodiments, the vehicle can proceed at an approximately constant velocity, such that track 3802 proceeds at an approximately constant velocity in a first direction (e.g., right to left in FIG. 38 ) with respect to plant bed 3801. In many embodiments, RPC 3803 can move with respect to track 3802, such as explained above for RPC 3260 and RPC track 3336 in connection with FIGS. 36-37 . In many embodiments, the movement of RPC 3803 with respect to track 3802 can beneficially keep robots 3804-3807 in a stationary position with respect to plant bed 3801.

As shown in FIG. 38 , time views 3811 and 3812 are progressive time views during a first time period in which RPC 3803 is held in a first carrier position and stationary with respect to plant bed 3801 while track 3802 moves in the first direction with respect to plant bed 3801. While in the first carrier position, the robots (e.g., 3804-3807) can be carried in a stationary manner at a first set of robot positions, such that robot 3807 is carried in a stationary manner at plant 3821, robot 3806 is carried in a stationary manner at plant 3881, robot 3805 is carried in a stationary manner at plant 3824, and robot 3804 is carried in a stationary manner at plant 3884. As shown in time views 3811 and 3812, RPC 3803 is held in the first carrier position and the first set of robot positions remains constant as track 3802 proceeds in the first direction. To achieve this station-keeping of RPC 3803, RPC 3803 can move with respect to track 3802 in a second direction that is opposite the first direction at the same velocity that track 3802 moves in the first direction with respect to plant bed 3801.

At a time period extending between the time views shown in time views 3812-3813, RPC 3802 can move from the first carrier position to a second carrier position. The movement of RPC 3802 from the first carrier position to the second carrier position can be an adjacent progression. Adjacent progression can refer to the robots moving to a position immediately next to the previous position, such as moving to the next plant in a row of plants. To achieve this adjacent progression of RPC 3803, RPC 3803 can move with respect to track 3802 in the first direction while track 3802 continues to move in the first direction respect to plant bed 3801, such that RPC 3803 moves fasted in the first direction with respect to plant bed 3801 than track 3802 moves in the first direction with respect to plant bed 3801.

Time views 3813 and 3814 are progressive time views during a second time period in which RPC 3803 is held in the second carrier position and stationary with respect to plant bed 3801 while track 3802 moves in the first direction with respect to plant bed 3801. While in the second carrier position, the robots (e.g., 3804-3807) can be carried in a stationary manner at a second set of robot positions, such that robot 3807 is carried in a stationary manner at plant 3822, robot 3806 is carried in a stationary manner at plant 3882, robot 3805 is carried in a stationary manner at plant 3825, and robot 3804 is carried in a stationary manner at plant 3885. As shown in time views 3813 and 3814, RPC 3803 is held in the second carrier position and the second set of robot positions remains constant as track 3802 proceeds in the first direction. To achieve this station-keeping of RPC 3803, RPC 3803 can move with respect to track 3802 in a second direction that is opposite the first direction at the same velocity that track 3802 moves in the first direction with respect to plant bed 3801.

At a time period extending between the time views shown in time views 3814-3815, RPC 3802 can move from the second carrier position to a fourth carrier position. The movement of RPC 3802 from the second carrier position to the fourth carrier position can be an adjacent progression. To achieve this adjacent progression of RPC 3803, RPC 3803 can move with respect to track 3802 in the first direction while track 3802 continues to move in the first direction respect to plant bed 3801, such that RPC 3803 moves fasted in the first direction with respect to plant bed 3801 than track 3802 moves in the first direction with respect to plant bed 3801.

Time views 3815 and 3816 are progressive time views during a fourth time period in which RPC 3803 is held in the fourth carrier position and stationary with respect to plant bed 3801 while track 3802 moves in the first direction with respect to plant bed 3801. While in the fourth carrier position, the robots (e.g., 3804-3807) can be carried in a stationary manner at a fourth set of robot positions, such that robot 3807 is carried in a stationary manner at plant 3823, robot 3806 is carried in a stationary manner at plant 3883, robot 3805 is carried in a stationary manner at plant 3826, and robot 3804 is carried in a stationary manner at plant 3886. As shown in time views 3815 and 3816, RPC 3803 is held in the fourth carrier position and the fourth set of robot positions remains constant as track 3802 proceeds in the first direction. To achieve this station-keeping of RPC 3803, RPC 3803 can move with respect to track 3802 in a second direction that is opposite the first direction at the same velocity that track 3802 moves in the first direction with respect to plant bed 3801.

At a time period extending between the time views shown in time views 3816-3817, RPC 3802 can move from the fourth carrier position to a third carrier position. The movement of RPC 3802 from the fourth carrier position to the third carrier position can be a leap-frog progression. Leap-frog progression can refer to the robots moving to a position that is not immediately next to the previous position and which skips (or “leap over”) other positions that have already been serviced, such as moving from a plant in a row of plants to another plant in a row of plants that is beyond other plants that have already been picked. To achieve this leap-frog progression of RPC 3803, RPC 3803 can move with respect to track 3802 in the first direction while track 3802 continues to move in the first direction respect to plant bed 3801, such that RPC 3803 moves fasted in the first direction with respect to plant bed 3801 than track 3802 moves in the first direction with respect to plant bed 3801. In many embodiments, RPC 3803 can move faster in the first direction with respect to track 3802 during the leap-frog progression than during the adjacent progression.

Time view 3817 is a time view during a third time period in which RPC 3803 is held in the third carrier position and stationary with respect to plant bed 3801 while track 3802 moves in the first direction with respect to plant bed 3801. While in the third carrier position, the robots (e.g., 3804-3807) can be carried in a stationary manner at a third set of robot positions, such that robot 3807 is carried in a stationary manner at plant 3827, robot 3806 is carried in a stationary manner at plant 3887, robot 3805 is carried in a stationary manner at plant 3830, and robot 3804 is carried in a stationary manner at plant 3890. RPC 3803 is held in the third carrier position and the third set of robot positions remains constant as track 3802 proceeds in the first direction. To achieve this station-keeping of RPC 3803, RPC 3803 can move with respect to track 3802 in a second direction that is opposite the first direction at the same velocity that track 3802 moves in the first direction with respect to plant bed 3801. In many embodiments, the process can repeat similarly as explained in the progression of time views 3811-3817 in the progressed robot positions to continue positioning the robots at progressed plant positions for plants 3828, 3829, 3831-3835, and so forth for plant row 3902, for plants 3888, 3889, 3891-3895, and so forth for plant row 3901.

At each set of robot positions, the robots (e.g., 3804-3807) can perform tasks simultaneously. For example, if robots 3804-3807 are harvesting robots (e.g., harvesting robot 100 (FIG. 1 ), harvesting robot 2000 (FIG. 20 )), robots 3804-3807 can each independently and simultaneously rotate around the plants at the set of robot positions to detect and pick crops from the plants. In many embodiments, the times at which the robots (e.g., 3804-3807) are kept at each of the set of robot positions can depend on the nature of the task. For example, for picking crops using harvesting robots, RPC 3803 can remain at each set of robot positions for a set time, such as 8 seconds, or another suitable time required for picking crops. For another type of robots, such as hole-punching robots, the time at each position can be shorter, such as 1 second, or another suitable time period. In many embodiments, the movement from a set of robot positions to the next set of robot positions for an adjacent progression can be a suitable time required to move RPC 3803 to the next set of robots positions. For example, for picking crops using harvesting robots, RPC 3803 can perform the adjacent progression during a set time, such as 1.5 seconds, or another suitable time required for moving RPC 3803 in the adjacent progression. In many embodiments, the movement from a set of robot positions to the next set of robot positions for a leap-frog progression can be a suitable time required to move RPC 3803 to the next set of robots positions when leap-frogging other sets of robot positions. For example, for picking crops using harvesting robots, RPC 3803 can perform the leap-frog progression during a set time, such as 2.5 seconds, or another suitable time required for picking crops, or another suitable time required for moving RPC 3803 in the leap-frog progression.

In many embodiments, the station-keeping of RPC 3803 in each set of robot positions can advantageously allow the vehicle (e.g., harvesting vehicle 3200 (FIGS. 32-34 ) to move at an approximately constant velocity, such that the vehicle does not need to start and stop between each set of robot positions, and such that the vehicle can avoid wasted time required to start and stop and the large amount of wasted energy necessary to accelerate and decelerate the vehicle at each start and stop.

Turning ahead in the drawings, FIG. 40 illustrates a top view of rows of plant beds 4000 showing a vehicle 4001 in a progression of time views 4011-4013 as vehicle 4001 moves through rows of plant beds 4000. Vehicle 4001 is merely exemplary, and embodiments of the vehicle are not limited to embodiments presented herein. The vehicle can be employed in many different embodiments or examples not specifically depicted or described herein. Vehicle 4001 can be similar or identical to vehicle 3200 (FIGS. 32-34 ), and can show only portions of vehicle 3200 for clarity. For example, vehicle 4001 can include a body with four RPC tracks 4004-4007, which can be similar or identical to RPC tracks 3334-3337 (FIGS. 33-34 ), and can carry RPCs, such as RPCs 3240, 3250, 3260, and 3270 (FIGS. 32-34 ), respectively, but not shown here in FIG. 40 . In many embodiments, vehicle 4001 can include wheels at each side of vehicle 4001, such as wheels 4002 at a first side of vehicle 4001 and wheels 4003 at a second side of vehicle 4001.

In many embodiments, vehicle 4001 can move through rows of plant beds 4000, which can include plant beds, such as plant beds 4021-4032, and rows, such as rows 4041-4051, between the plant beds (e.g., 4021-4032). In several embodiments, wheels 4002-4003 can roll along rows (e.g., 4041-4051) between the plant beds (e.g., 4021-4032). For example, in some embodiments, as shown in time view 4011, wheels 4002 can roll along row 4047 and wheels 4003 can roll along row 4041, such that vehicle 4001 straddles six plant beds (e.g., plant beds 4021-4027), and can be used to harvest and/or punch holes in four plant beds (e.g., plant beds 4023-4026) at a time. For example, track 4004 can be positioned over plant bed 4026, track 4005 can be positioned over plant bed 4025, track 4006 can be positioned over plant bed 4024, and track 4007 can be positioned over plant bed 4023. In other embodiments, vehicle 4001 can straddle more or fewer plant beds and can harvest more or fewer plant beds at a time. Vehicle 4001 can progress along the rows (e.g., 4041, 4047) in a first direction to harvest and/or punch holes on the plant beds (e.g., 4023-4026), such as right to left in FIG. 40 . The rows can be straight or curved.

As shown in time view 4012, after reaching the end of the rows (e.g., 4023-4026), vehicle 4001 can turn wheels 4002 and 4003 at a right angle to proceed to a next set of rows. After reaching the next set of rows, vehicle 4001 can again turn wheels 4002 and 4003 at a right angle to proceed along the next set of rows in a second direction that is opposite the first direction, such as left to right in FIG. 40 . In many embodiments, each wheel (e.g., 4002, 4003) can turn independently.

As shown in time view 4013, wheels 4002 can roll along row 4045 and wheels 4003 can roll along row 4051, such that vehicle 4001 straddles six plant beds (e.g., plant beds 4026-4031), and can be used to harvest and/or punch holes in four plant beds (e.g., plant beds 4027-4030) at a time. For example, track 4004 can be positioned over plant bed 4030, track 4005 can be positioned over plant bed 4029, track 4006 can be positioned over plant bed 4028, and track 4007 can be positioned over plant bed 4027. Vehicle 4001 can similarly progress along rows of plant beds 4000 in a serpentine fashion to process each row of plant beds 4000. In many embodiments, vehicle 4001 can be guided by a guidance control system, as explained below in greater detail.

In many embodiments, vehicle 4001 can be used to punch holes for planting plants for crops (e.g., strawberries or other crops) carry harvesting robots (e.g., 100 (FIG. 1 ), 2000 (FIGS. 20-21 )) for picking crops (e.g., strawberries or other crops). In many embodiments, a guidance control system can position RPCs (e.g., 3240, 3250, 3260, 3270 (FIGS. 32-34 )), which can carry hole-punching robots to punch holes, as shown in FIG. 43 and described below, to carry harvesting robots (e.g., 100 (FIG. 1 ), 2000 (FIGS. 20-21 )), or other suitable robots. In many embodiments, the robots can be positioned to perform tasks (e.g., hole punching, picking crops, etc.) by the guidance control system based on a location from GPS receivers (e.g., GPS receivers 3215-3216 (FIGS. 32-34 )) and/or other approaches, such as those described below.

For many types of plants, there are three phases in a lifecycle of the plants in the field, namely planting, growing, and harvesting. At the outset, there are no plants in the field, and as such the placement and positioning of the plants is not established. In some embodiments, the guidance control system can calculate target plant locations based on an initial reference position and a heading. These target plant locations can then be used to position the RPCs (e.g., 3240, 3250, 3260, 3270 (FIGS. 32-34 )) and robots carried by the RPCs to punch the holes for the actual plants. In a number of embodiments, the actual plant locations can be stored in a database for later use. In some embodiments, the plant locations can be stored based on a reference position and a heading, with offsets calculated based on fixed spacing between plants.

Knowing the plant locations accurately can be an important aspect in facilitating the positioning of vehicle 4001 over the center of the plants in a repeatable manner. However, the nature of commercial, stand-alone GPS generally contains error sources that combine to influence the position error of the GPS solution over time. Standard Positioning Service (SPS) GPS positioning can contain horizontal errors on the order of 10 meters (m). Wide-area augmentation types, such as WAAS (Wide Area Augmentation System) in the United States, can reduce that error to meter-level, with additional augmentation services and techniques reducing the error even further, down to decimeter-level for local-area differential GPS (LADGPS), and centimeter-level accuracy for Real-Time Kinematic (RTK) systems.

Accurate positioning of vehicle 4001 facilitates accurate determination of the RPCs (e.g., 3240, 3250, 3260, 3270 (FIGS. 32-34 )) and robots carried by the RPCs, which, when combined with knowledge of the multiple robot positions on the RPC and/or plant locations, can be used to perform tasks with multiple robots at the same time (e.g., picking multiple plants at the same time).

A potential challenge when trying to hold sub-inch accuracy with GPS alone is that commercially available GPS systems are generally only accurate down to 0.433 inches (1.10 cm) when using RTK, and may have a slow refresh rate. While moving at approximately 1 mile per hour (mph) (1.61 kilometers per hour (kph)), with a 20 Hertz (Hz) position output from the GPS, vehicle 4001 can move 0.12 inch (0.30 cm) every second, and 0.0061 inch (0.0154 cm) between each GPS position refresh. Slower refresh rates, or a faster harvester speed, can result in a greater distance traveled between each GPS position refresh. Some embodiments may work around a slower refresh rate by using a combination of GPS and dead reckoning using a velocity of vehicle 4001 to estimate the current position of the harvester.

When rows (e.g., rows 4041-4051) are on 50 inch (127 cm) centers, with the distance between plants being even smaller, such distances can lead to inaccuracies due to floating point rounding during the computation process utilizing a purely latitude and longitude-based reference system. Computing geographical distance using the law of cosines can cause such errors over small distances, as the cosine value approaches 1.0. Alternatives, such as the Haversine formula, can suffer from error derived from treatment of the Earth as a sphere, rather than an oblate spheroid. Vincenty's solutions can offer advantages suited to the needs of plant location calculations. Vincenty's solutions are derived as two iterative methods: (a) a direct solution, which computes a second point given an initial position, a bearing (heading), and a distance; and (b) an inverse solution, which computes the distance and bearing between two points

The start location of a row can be given by either an area around a start point or by a start line defined by two points. A distance can then be calculated from the start location for each of the plants in the row. The distance traveled can then be calculated as the tractor moves down the row by using a number of different inputs such as GPS-based velocity, ground-based velocity, the time from last GPS update, last GPS location, and/or direction of travel. With this, a more accurate estimate of the distance travelled can be calculated than with just using GPS locations alone.

In the eyes of advance planning, some embodiments may traverse the row with vehicle 4001 to get the start and stop coordinates for each row along with the travel direction (heading) of the row. From there, the start locations of each row can be calculated from the start location of the first row in the set.

When calculating the plant locations using a latitude/longitude system, the use of Vincenty's direct solution allows for calculation of a position given an initial position, a bearing, and a distance. This can form a two-part solution to find the origin of each row, given the field starting point and the direction the rows are to run, and the distance between each row, and the location of each plant in the row, given the direction the rows are to run and the distance between each plant.

For the first step of the process, the equation below gives the origin position for each row:

$\left( {\phi_{{row},i},\lambda_{{row},i}} \right) = {\mathcal{V}\left( {\phi_{0},\lambda_{0},{\psi_{field} \pm \frac{\pi}{2}},{\delta{row}}} \right)}$

where ϕ_(row,i) and λ_(row,i) are the latitude and longitude, respectively, of the start of the row, ϕ₀ and λ₀ are the latitude and longitude, respectively, of the field origin point, ψ_(field) is s the heading of the field's rows, (Vow is the distance between rows, and the function

(x) is Vincenty's direct solution.

Once the origin position for each row is known, the position of each plant in the row can be calculated:

(ϕ_(plt,n),λ_(plt,n))=

(ϕ_(row,i),λ_(row,i),ψ_(field),δplt)

where ϕ_(plt,n) and λ_(plt,n) are the latitude and longitude, respectively, of the n^(th) plant in the row, ϕ_(row,i) and λ_(row,i) are the latitude and longitude, respectively, of the start of the row, ψ_(field) is the heading of the field's rows, δplt is the distance between plants in the row, and the function

(x) is Vincenty's direct solution.

In order to accurately place the robots over each plant, the location of the GPS with respect to each row as well as the location of the RPC (Robot Position Carrier) with respect to the phase center of the GPS antenna can be determined. Accurately knowing all these values in order to hold +/−0.75 inch (1.90 cm) tolerance on the robots can present challenges. As discussed above, the accuracy of GPS is at best 0.433 inch (1.10 cm), which uses up most of the tolerance. Another possible issue is that a slow refresh rate for GPS position output can cause uncertainty with the current position and velocity of vehicle 4001 if the drive system of vehicle 4001 causes unanticipated acceleration or deceleration to occur between updates.

Turning ahead in the drawings, FIG. 41 illustrates a top view of a vehicle 4001, showing an X-axis and a Y-axis in a coordinate system for a guidance control system. FIG. 42 illustrates a rear view of a vehicle 4001, showing a Y-axis and a Z-axis in the coordinate system of FIG. 41 for a guidance control system. When discussing items such as platform attitude and lever arms, the guidance control system can use a defined reference frame from which to derive measurements and to assign axes of rotation for the platform attitude parameters. Viewing movement and translations from the perspective of a theoretical driver on vehicle 4001 can be defined by a “body frame” of vehicle 4001, denoted by B with a subscript for each axis (e.g., B_(x), B_(y), B_(z)). The body frame B can be defined as a right-hand coordinate system, with the positive X-axis pointing in the direction shown in FIG. 41 , which can be in the same direction of tracks 4004-4007, and the positive Y-axis pointing in a direction from wheels 4003 to wheels 4002, as shown in FIG. 41 . As the coordinate system is right-handed, the positive Z axis can point downward from the bottom of the platform towards the ground, as shown in FIG. 42 .

The direction of travel can change if the harvester platform is driven along a row in the opposite direction, but the body frame axes described here will not change with the direction of travel. With the body frame axes defined, as shown in FIGS. 41-42 , attitude parameters, specifically, roll, pitch, and yaw, can be defined. Roll is a rotation about the body-X axis, tilting the platform from side to side. Pitch is a rotation about the body-Y axis, and is equivalent to tilting the platform forward or backward. Yaw is about the body-Z axis, and is the direction the platform is facing.

Each GPS receiver (e.g. 3215-3216 (FIGS. 32-34 )) can provide the calculated position of the phase center of the antenna of the GPS receiver (e.g. 3215-3216 (FIGS. 32-34 )). This calculated position can be used to navigate vehicle 4001, although the physical mounting location of the GPS receiver (e.g. 3215-3216 (FIGS. 32-34 )) on the frame pieces (e.g., 3211-3212 (FIGS. 32-34 )) are is usually not ideal for this purpose because of clear-sight line blockages. In many embodiments, GPS receivers (e.g., 3215-3216 (FIGS. 32-35 )) can be mounted on the top of vehicle 4001, such as on arms 3213-3214 (FIGS. 32-34 ), respectively, as shown on harvesting vehicle 3200 (FIGS. 32-34 ) to allow for clear sight lines, which can facilitate improved GPS reception

In order to provide a position that is conducive for autonomous navigation, the GPS position can be referenced to a guidance control point (GCP) 4100. GCP 4100 can serve as a reference for calculating other locations on vehicle 4001, such as positions of each RPC (e.g., 3240, 3250, 3260, 3270 (FIGS. 32-34 )) and each robot (e.g., 3461-3464 (FIG. 34 )) carried by each RPC (e.g., 3240, 3250, 3260, 3270 (FIGS. 32-34 )). The GCP can be used as the reference point when navigating vehicle 4001. Calculating the position of GCP 4100 from the GPS position can involve incorporating lever arm information for each of the GPS receivers (e.g., 3215-3216 (FIGS. 32-34 )) on arms 3213-3214 (FIGS. 32-34 ) with respect to GCP 4100.

The lever arm information for the GPS receivers (e.g., 3215-3216 (FIGS. 32-34 )) can be determined through measurement, either on vehicle 4001 itself or through the use of a modeling program to determine the distances. In most embodiments, the guidance control system can incorporation additional lever arm information for each of the robots. This lever arm information for the robots, when used in conjunction with the lever arm information for the GPS receivers (e.g., 3215-3216 (FIGS. 32-34 )) can allow for the position of each robot to be calculated based on the position of the GPS receivers (3215-3216 (FIGS. 32-34 )). If the assumptions can be made that the RPC (e.g., 3240, 3250, 3260, 3270 (FIGS. 32-34 )) is aligned with the body-forward (X) axis, the absolute position of each robot, u, can be determined.

The attitude, namely heading, pitch, and roll, of vehicle 4001 can be used to form a Direction Cosine Matrix (DCM) relating the attitude of vehicle 4001 to the north-pointing navigation frame. This DCM, called is shown below:

$C_{B}^{N} = \begin{bmatrix} {\cos\theta\cos\psi} & {{{- {c{os}}}\phi\sin\psi} + {\sin\phi\sin\theta\cos\psi}} & {{\sin\phi\sin\psi} + {\cos\phi\sin\theta\cos\psi}} \\ {\cos\theta\sin\psi} & {{\cos\phi\cos\psi} + {\sin\phi\sin\theta\sin\psi}} & {{{- s}{in}\phi\cos\psi} + {\cos\phi\sin\theta\sin\psi}} \\ {{- s}{in}\theta} & {\sin\phi\cos\theta} & {\cos\phi\cos\theta} \end{bmatrix}$

where ψ is the heading of the vehicle 4001, θ is the pitch, and ϕ is the roll.

Attitude measurement with only two GPS antennas can suffers from a lack of adequate degrees of freedom to truly measure all 3 axes of rotation. Since any rotation about the axis formed between the two receivers is invisible without external aiding, only two components of platform attitude (i.e., (a) heading and (b) either pitch or roll) can be measured.

In order to alleviate the missing degree of freedom, assumptions can be made about the platform, such that it is approximately level at all times, or that the platform's roll (as it exists across the longest dimension of the harvester platform) is negligible. However, this approach eliminates any possibility of GPS-only measurement of the missing axis to aid in leveling of the harvester platform itself, and does not allow for measurement of potentially sloped areas (e.g., California fields).

Error in determination of the horizontal position of the RPC (e.g., 3240, 3250, 3260, 3270 (FIGS. 32-34 )) is dominated by heading error, rather than pitch or roll. Some embodiments may use two GPS receivers, or a dual-antenna GPS receiver, to calculate the platform heading. Using the accuracy of RTK GPS coupled with a separation of several meters between antennas (or receivers) can reduce the heading error to less than a few tenths of a degree.

In order to provide visibility to the remaining aspects of the attitude of vehicle 4001, namely pitch and roll, a low-cost Inertial Measurement Unit (IMU) consisting of a triad of orthogonal accelerometers (“accels”) and gyroscopes (“gyros”) to measure the inertial accelerations of vehicle 4001, allowing for a pitch and roll attitude solution to be calculated without the use of GPS data. In many embodiments, vehicle 4001 can include an IMU, such as in a GPS receiver (e.g., 3215 or 3216 (FIGS. 32-34 )) or at another position.

By itself, an inertial measurement system using low-cost sensors can be not sensitive enough to determine the platform heading, as it can merely determine the offset from the initial starting point as measured by the gyros. Use of a multiple GPS (or a multi-antenna GPS) system can allow for an absolute heading reference, which can be aided by gyro measurements to account for a loss of GPS, if desired. The low dynamic environment of vehicle 4001 and the clear-sky nature of a farm combine to make this a low probability occurrence.

In order to compute the lever arm calculations using geodetic coordinates, some intermediary calculations can be performed by the guidance control system. These calculations can be made with the same assumptions described above. The body frame to navigation frame matrix can be applied to the lever arm information for the RPCs (e.g., 3240, 3250, 3260, 3270 (FIGS. 32-34 )) (e.g. lever arm for RPC in the X axis (LA_(RPC,X)), lever arm for RPC in the Y axis (LA_(RPC,Y)), and lever arm for RPC in the Z axis (LA_(RPC,Z)), with the body-X axis adjusted based on the distance (δPos_(RPC)) of the RPC (e.g., 3240, 3250, 3260, 3270 (FIGS. 32-34 )) from home, to form the lever arm distance offsets in terms of the north, east, and downward (as with body frame, positive being downward) (NED) axes.

${LA_{{RPC},{NED}}} = {C_{B}^{N}\begin{bmatrix} {{LA_{{RPC},X}} + {\delta{Pos}_{RPC}}} \\ {LA_{{RPC},Y}} \\ {LA_{{RPC},Z}} \end{bmatrix}}$

The equations for application of a lever arm to a position can be derived from equations used to calculate a change in position due to a velocity. If the assumption is made that the lever arm distances is actually a velocity over a 1 second period, the change in position formulas can be used to compute the change in latitude (δϕ) and longitude (δλ).

${\delta\phi} = \frac{v_{N}}{R_{M} + h}$ ${\delta\lambda} = \frac{v_{E}\sec\phi}{R_{T} + h}$

where ϕ is the current latitude, h is the current elevation,

_(N) is the velocity in the north direction, and

_(E) is the velocity in the east direction. R_(M) is the meridional radius of curvature, and R_(T) is the transverse radius of curvature of the Earth, such that:

$R_{M} = \frac{R_{P}\left( {1 - e^{2}} \right)}{\sqrt{1 - {e^{2}\sin^{2}\phi}}}$ $R_{T} = \frac{R_{P}}{\sqrt{1 - {e^{2}\sin^{2}\phi}}}$

where R_(P) is the polar radius, R_(P)=6378137.0m, and e² is the eccentricity of the ellipsoid, e²≅0.00669438.

Once the position change due to the lever arm has been calculated, the position change can be applied to the GPS position:

ϕ_(RPC)=ϕ_(GPS)+δϕ

λ_(RPC)=λ_(GPS)+δλ

where ϕ_(RPU) is the latitude of the RPC, λ_(RPU) is the longitude of the RPC, ϕ_(GPS) is the latitude of the GPS, and λ_(GPS) is the longitude of the GPS.

Due to the length of the berry picking season, there is a source of positional error that slowly grows over time due to the movement of the continental plates. The plates themselves move anywhere from 1 to 10 cm per year, eating into the positioning error budget. Using standard GPS, this measurement error can be lost in the noise and uncertainty present in the system, but with RTK GPS, this error will show up as a position bias at a later time if no compensation is used. In order to compensate for this, the base station position can be surveyed before planting, and then surveyed again before harvesting is to be performed. Some embodiments may apply the position difference as an offset to the stored plant locations.

In many embodiments, the guidance control system advantageously can provide positioning accuracy for each robot within 0.5 inch (1.27 cm). In some embodiments, the positioning accuracy for each robot using the guidance control system can be more precise, such as within 0.25 in (0.635 cm), which has been measured in testing of the guidance control system. In many embodiments, the guidance control system can facilitate precision agriculture, such that each individual plant location (e.g., for plant, growing, and/or harvesting) is tracked. In several embodiments, precision agriculture provided by the guidance control system can allow picked crops to be traced to the individual plant or limited group of individual plants from which the crops were picked. For example, a package of strawberries can include an identifier that can be used to trace the strawberries picked to a group of plants (e.g., 8 plants, or another suitable number of plants) at tracked locations.

Turning ahead in the drawings, FIG. 43 illustrates a top view of a plant bed 4300, showing holes punched for growing plants. As explained above, in many embodiments, the robots of vehicle 4001 (FIG. 40 ) or harvesting vehicle 3200 (FIGS. 32-34 ) can include hole punching robots (e.g., in harvesting vehicle 3200 (FIGS. 32-34 ), the harvesting robots (e.g., 3461-3464 (FIGS. 34-35 ) can be replaced with hole punching robots). For example, each hole punching robot can be a pneumatic actuator of a cylindrical shaft which can punch a hole in a plant bed, such as through plastic on a plant bed, to create a hole in order to plant a plant (e.g., a strawberry plant or other type of plant). In many embodiments, the vehicle (e.g., vehicle 4001 (FIG. 40 ) or harvesting vehicle 3200 (FIGS. 32-34 )) can carry the hole punch robots on the RPCs (e.g., 3240, 3250, 3260, 3270 (FIGS. 32-24 )) to punch rows of holes, such as rows of holes 4321 and 4322. For example, row of holes 4321 can include holes 4301, 4302, and 4303 in a row, and ow of holes 4322 can include holes 4311, 4312, and 4313 in a row. In many embodiments, each of the holes in a row can be approximately equally spaced. As indicated previously, the row can be straight or curved.

Turning ahead in the drawings, FIG. 44 illustrates a side view of suspension components 4400 for adjusting a vertical position of a wheel 4401 with respect to a body 4406. Suspension components 4400 are merely exemplary, and embodiments of the suspension components are not limited to embodiments presented herein. The suspension components can be employed in many different embodiments or examples not specifically depicted or described herein. In a number of embodiments, suspension components 4400 can include wheel 4401, an axle 4402, a wheel stanchion 4403, a turning assembly 4404, a wheel mount 4405, body 4406, adjustment mechanism 4407, and/or actuator 4408. Wheel 4401 can be similar or identical to wheels 3201-3204 (FIGS. 32-34 ) and/or 4002-4003 (FIGS. 40-43 ). Body 4406 can be a portion of body 3210 (FIGS. 32-34 ), such as a portion of arms 3213-3214 (FIGS. 32-24 ).

In many embodiments, wheel 4401 can be coupled to and rotate around axle 4402, which can be coupled to wheel stanchion 4403. In various embodiments, wheel stanchion 4403 can be movably coupled to wheel mount 4405 by turning assembly 4404, which can allow wheel 4401 to be turned in a different direction. In several embodiments, wheel mount 4405 can be movably coupled to body 4406 by adjustment mechanism 4407, which can be a slidably coupling or another suitable coupling, which can allow wheel mount 4405 to adjust vertically with respect to body 4406. In several embodiments, wheel mount 4405 can be adjusted vertically up or down with respect to body 4406 with actuator 4408. Actuator 4408 can be a hydraulic or electric actuator, for example. In several embodiments, actuator 4408 can be controlled by a suspension control system, such as suspension control system 5803 (FIG. 58 , described below), which in some embodiments can be an active suspension system.

In various embodiments, the suspension control system (e.g., 5803 (FIG. 58 , described below)) can control the vertical position of wheel 4401 with respect to body 4406. When wheel 4001 is on a surface, adjusting the vertical position of wheel 4001 with respect to body 4406 can raise or lower body 4406 with respect to the surface. In many embodiments, the assembly for each wheel on the vehicle (e.g., wheels 3201-3204 (FIGS. 32-34 ) on harvesting vehicle 3200 (FIG. 32 ) and/or 4002-4003 (FIGS. 40-43 ) on vehicle 4001 (FIG. 40 )) can include suspension components 4400. In some embodiments, suspension components can provide for a range of vertical adjustment of wheel 4401 with respect to body 4406. For example, in some embodiments, the range of vertical adjustment of wheel 4401 with respect to body 4406 can be 10 inches (25.4 cm). In other embodiments, the range of vertical adjustment can be more or less than 10 inches (25.4 cm).

Turning ahead in the drawings, FIG. 45 illustrates a perspective view of a vehicle 4500, showing a body 4520 of vehicle 4500 in a lowered suspension position. FIG. 46 illustrates a perspective view of vehicle 4500, showing a body 4520 of vehicle 4500 in a raised suspension position. Vehicle 4500 is merely exemplary, and embodiments of the vehicle are not limited to embodiments presented herein. The vehicle can be employed in many different embodiments or examples not specifically depicted or described herein. Vehicle 4500 can be similar or identical to vehicle 4001 (FIG. 40 ) and/or harvesting vehicle 3200 (FIGS. 32-34 ), and various components of vehicle 4500 can be similar or identical to vehicle 4001 (FIG. 40 ) and/or harvesting vehicle 3200 (FIGS. 32-34 ).

In many embodiments, vehicle 4500 can include a body 4520 and wheels 4501-4504, which can each be part of associated suspension components 4511-4514, respectively. Suspension components 4511-4514 each can be similar or identical to suspension components 4400 (FIG. 44 ), and can raise and/or lower the vertical position of wheels 4501-4504, respectively, with respect to body 4520.

In many embodiments, suspension components 4511-4514 for each wheel 4501-4504 can operate independently from the other suspension components (e.g., 4511-4514). In many embodiments, one or more of suspension components 4511-4514 can allow one or more of wheels 4501-4504 to be vertically adjusted with respect to the body while not adjusting other wheels (e.g., 4501-4504). In some embodiments, suspension components 4511-4514 can adjust wheels 4501-4504 at different vertical adjustment amounts. For example, as shown in FIG. 45 vehicle 4500 can be positioned lower than vehicle 4500 in FIG. 46 .

In many embodiments, vehicle 4500 can carry one or more robots, such as harvesting robots 3461-3464 (FIGS. 34-35 ) in harvesting vehicle 3200 (FIGS. 32-34 ). In many embodiments, each robot can determine a height of the robot from the plant bed (e.g., plant beds 3281-3290 (FIGS. 32-34 )), such as by using imaging sensors (e.g., imaging sensors 1290-1291 (FIGS. 12-13 ) and/or images sensors 2190-2191 (FIG. 21 )) on the robots. For example, the imaging sensors can determine that a robot (not shown) on vehicle 4500 in FIG. 45 is at a height 4550 from the plant bed. Similarly, the imaging sensors can determine that a robot (not shown) on vehicle 4500 in FIG. 45 is at a height 4650 from the plant bed, such that height 4650 is greater than height 4550 (FIG. 45 ). In some embodiments, the height information can be determined by the robot based on the imaging sensors determining the distance from the imaging sensors to the crops to be picked. In other embodiments, the height information can be determined by the robot based on the distance from the imaging sensors to the plant bed.

In many embodiments, more than one robot attached to vehicle 4500 can provide height information to the suspension control system (FIG. 58 , described below). For example, in some embodiments, each robot can provide height information to the suspension control system (FIG. 58 , described below). In many embodiments, the suspension control system (FIG. 58 , described below) can receive the height information from the robots and determine how to control the adjustment of the vertical position of one or more of wheels 4501-4504. In a number of embodiments, the adjustment of one or more wheels (e.g., 4501-4504) can be based on the height information of one or more robots close to the one or more wheels (e.g., 4501-4504). In other embodiments, the adjustment of one or more wheels (e.g., 4501-4504) can be based on an average of height information from all of the robots. In other embodiments, the adjustment of each wheel (e.g., 4501-4504) can be the same for each wheel (e.g., 4501-4504) based on the height information received from one or more robots.

In some embodiments, the height information can be received from the robots regularly, such as on a cycle, and the suspension control system (FIG. 58 , described below) can provide adjustment control for the one or more wheels (e.g., 4501-4504) regularly based on updated information received each cycle and/or over a period of cycles. For example, the height information can be sent from the robots to the suspension control system (FIG. 58 , described below) on a 1 Hz cycle, a 2 Hz cycle, a 4 Hz cycle, or another suitable cycle.

In a number of embodiments, vehicle 4500 (FIG. 45 ) can operate in an open field subject to weather. The fields can be leveled and setup initially to relatively tight specifications upon initiation, but due to this weather exposure, various areas of the field can be subject to settling or washout due to water and/or wind erosion. To deal with this issue and keep the robots within preferred inspection distances for picking speed considerations, vehicle 4500 can be equipped in several embodiments with the suspension control system (FIG. 58 , described below) to maintain a level of vehicle 4500, row orientation, and/or proper height above the plant beds for the robots.

In many embodiments, the adjustment of the vertical position of one or more wheels (e.g., 4501-4504), as controlled by the suspension control system (FIG. 58 , described below), can beneficially keep the robots from crashing into the plant beds as they are carried by vehicle 4500, for example. For example, if a wheel (e.g., 4501-4504) of vehicle 4500 start to dip into a washed out area, the suspension control system (FIG. 58 , described below) can detect the lowering of the height information from one or more of the robots, and can adjust at least the wheel (e.g., 4501-4504) to compensate and level body 4520 and/or keep the robots a distance from the plant beds.

In some embodiments, for example, a bottom most part of each of the picking system, excluding the gripper in the picking position that is being lowered to pick the crop, can be kept at a distance above the plant bed. For example, the distance can be 2.0 inches (5.08 cm) to 5.0 inches (12.7 cm). In other embodiments, the distance can be another suitable distance. In a number of embodiments, the suspension control system (FIG. 58 , described below) can keep the bottommost part of the robot from the plant bed when the robot is moving with respect to the plant bed and/or when the robot is being held stationary with respect to the plant bed by the RPC (e.g., 3240, 3250, 3260, 3270 (FIG. 32 )).

Strawberry plants can benefit from trimming off the dead, older growth that gets pushed out from the center of the plant as new growth appears. This trimming can prevent diseases caused by the rotting of older-organic debris. Typically, the resources available to do this trimming by hand are not available on farms due to the labor-intensive process. One of the issues with trimming the plants is that, if diseases are present on one plant, the disease can spread to adjacent plants by using common trimming utensils.

In some embodiments, a robot, such as harvesting robots 100 (FIG. 1 ) and/or 2000 (FIG. 20 ), and/or leaf displacement system 2800 (FIGS. 28-31 ), can include a cauterizing cutting hot wire or mechanical sickle bar that can slice off the outside older growth as the robot circles the plant or the leaf displacement system captures and holds the foliage (e.g., 1512, as shown in FIG. 20 ). The razor action and heating of the wire moving across the old outer growth can slice off the vines, which can trim the plant back to the newer inner growth. The older growth can then fall away from the plant after being mechanically stimulated by the robot and/or environmental factors, such as wind or rain. The hot wire can beneficially sterilize the wire so that, if diseases are present on the trimmed growth, they will not be passed to plants trimmed downstream of the diseased plant.

In several embodiments, pick deck 5920 can include a front cross support piece 6181 and a rear cross support piece 6182, which, in addition to cross frame pieces 6031-6032, can provide structural support for pick deck across the span of pick deck 5920 as pick deck 5920 is used to harvest across multiple plant beds. In many embodiments, RPCs tracks 6134-6137 can be attached to cross frame pieces 6031-6032. In several embodiments, pick deck 5920 can include various lift points, such as lift points 6125-6128. In a number of embodiments, pick deck 5920 can include four lift points (e.g., 6125-6128), each of which can be located at a different quadrant of pick device 5920. For example, lift point 6125 can be located at a front right quadrant of pick deck 5920, lift point 6126 can be located at a front left quadrant of pick deck 5920, lift point 6127 can be located at a rear right quadrant of pick deck 5920, and/or lift point 6128 can be located at a rear left quadrant of pick deck 5920. In many embodiments, lift points 6125-6128 can be attached to cross frame pieces 6031 and/or 6032. For example, lift points 6125-6126 can be attached to cross frame piece 6032, and/or lift points 6127-6128 can be attached to cross frame piece 6031.

In some embodiments, pick deck 5920 can include a various inline support pieces, such as inline support pieces 6183-6188. In many embodiments, the inline support pieces (e.g., 6183-6188) can extend from the front end of pick deck 5920 at front cross support piece 6181 to the rear end of pick deck 5920 at rear cross support piece 6182. In a number of embodiments, the inline support pieces (e.g., 6183-6188) can be spaced apart across the span of pick deck 5920 to provide additional structural support for pick deck 5920. For example, in some embodiments, such as shown in FIG. 61 (which is shown upside down from a bottom view), inline support piece 6183 can be located at a right-most side of pick deck 5920, inline support piece 6188 can be located at a left-most side of pick deck 5920, and inline support pieces 6184-6187 can be spaced approximately evenly between inline support piece 6183 and inline support piece 6188. In several embodiments, RPC tracks 6134-6137 can be attached to inline support pieces 6184-6187, respectively. In the same or other embodiments, RPC tracks 6134-6137 can be attached to cross frame pieces 6031-6032.

In several embodiments, pick deck 5920 can include an IMU support piece 6189, which can extend diagonally between cross frame piece 6031 and inline support piece 6183 proximate to IMU 6021. In many embodiments, IMU support piece 6189 can provide additional structural support for IMU 6021 so that the attitude measured by IMU 6021 can be closely aligned with the overall attitude of a top plane of pick deck 5920, as adjusted at lift points 6125-6128 attached to cross frame pieces 6031-6032, described below in further detail. In a number of embodiments, front cross support piece 6181, rear cross support piece 6182, cross frame pieces 6031-6032, inline support pieces 6183-6188, and/or IMU support pieces 6189 can provide a top frame for pick deck 5920, provide structural support for the components held by pick deck 5920, such as RPC tracks 6134-6137, RPCs 6140, 6150, 6160, 6170, and/or the robots (not shown in FIG. 61 ), and/or provide structural support for the cover pieces of pick deck 5920, such as top cover piece 6022, side cover 6023 (FIG. 60 ), and/or end cover piece 6024 (FIG. 60 ).

Proceeding to the next drawing, FIG. 62 illustrates a top, rear, left side perspective view of a portion of harvesting vehicle 5900 with top module 5930 (FIG. 59 ) removed, showing actuators 6255-6259 of harvesting vehicle 5900. As shown in FIG. 62 , body 5910 of harvesting vehicle 5900 can include actuators, such as actuators 6255-6258. In several embodiments, the actuators (e.g., 6255-6258) can be configured to adjust the position of pick deck 5920 with respect to body 5910 of harvesting vehicle 5900. For example, as shown in FIG. 62 , actuators 6255-6258 can be connected to lift points 6255-6258 of pick deck 5920. In several embodiments, actuators (e.g., 6255-6258) can be fixedly attached to a frame of 5920. For example, as shown in FIG. 62 , actuators 6256 and 6258 can be attached between frame piece 6011 and a left side support piece 6213, and actuators 6255 and 6257 can be attached between frame piece 6012 and a right side support piece 6214. In many embodiments, each of the actuators (e.g., 6255-6258) can be a rotary servo actuator, such as a brushless servo motor. In other embodiments, other suitable actuators can be used. In several embodiments, each actuator (e.g., 6255-6258) can be configured to lift sufficient weight, such that the actuators (e.g., 6255-6258) can collectively lift pick deck 5920. In some embodiments, for example, each actuator (e.g., 6255-6258) can lift approximately 1,500 pounds (680.4 kg). In other embodiments, each actuator (e.g., 6255-6258) can lift another suitable weight.

Turning ahead in the drawings, FIG. 63 illustrates a top, front, left side perspective view of a portion of pick deck 5920 and a portion of body 5910 with left side support piece 6213 partially cut out to show lifting elements when pick deck 5920 is in a fully lowered position. FIG. 64 illustrates a top, front, left side perspective view of a portion of pick deck 5920 and a portion of body 5910 with left side support piece 6213 partially cut out to show the lifting elements when pick deck 5920 is in a fully raised position. In many embodiments, as shown in FIGS. 63-64 , an actuator shaft 6361 of actuator 6256 can be fixedly attached an actuator arm 6362. In several embodiments, actuator arm 6362 can be rotatably attached to a rod 6364 at a joint 6363. In some embodiments, rod 6364 can be rotatably attached to lift point 6126 of pick deck 5920 at a joint 6365. Similarly, an actuator shaft 6371 of actuator 6258 can be fixedly attached an actuator arm 6372. In several embodiments, actuator arm 6372 can be rotatably attached to a rod 6374 at a joint 6373. In some embodiments, rod 6374 can be rotatably attached to lift point 6128 of pick deck 5920 at a joint 6375. In several embodiments, the other actuators (e.g., actuators 6255 and 6257 (FIG. 62 )) of body 5910 can be connected to pick deck 5920 using similar or identical elements. These elements can collectively be referred to as the lifting elements. In many embodiments, joints 6363, 6365, 6373, and/or 6375 can be ball joints.

In many embodiments, actuator 6256 can rotate actuator shaft 6361 to raise and/or lower lift point 6126 of pick deck 5920, and/or actuator 6258 can rotate actuator shaft 6371 to raise and/or lower lift point 6128 of pick deck 5920. Similarly, the other actuators (e.g., actuators 6255 and 6257 (FIG. 62 )) of body 5910 can be rotated to raise and/or lower lift points 6125 and 6127 (FIGS. 61-62 ) of pick deck 5920. In many embodiments, the actuators at the front of body 5910 (e.g., actuators 6255 (FIG. 62 ), 6256) can be configured to rotate the actuator shafts (e.g., 6361) such that the actuator arms (e.g., 6362) operate in the area frontward, but not in the area rearward, of the actuators (e.g., 6255 (FIG. 62 ), 6256) when rotating between a bottom center position, as shown in FIG. 63 , and a top center position, as shown in FIG. 64 , or vice versa, and the actuators at the rear of body 5910 (e.g., actuators 6257 (FIG. 62 ), 6258) can be configured to rotate the actuator shafts (e.g., 6371) such that the actuator arms (e.g., 6372) operate in the area rearward, but not in the area frontward, of the actuators (e.g., 6257 (FIG. 62 ), 6258) when rotating between a bottom center position, as shown in FIG. 63 , and a top center position, as shown in FIG. 64 , or vice versa.

For example, actuator 6256 can rotate actuator shaft 6361 clockwise, when viewed from the left, as shown in FIGS. 63-64 , when raising lift point 6126 from a bottom center position, as shown in FIG. 63 , to a top center position, as shown in FIG. 64 , and can rotate actuator shaft 6361 counterclockwise when lowering lift point 6126 from a top center position, as shown in FIG. 64 , to a bottom center position, as shown in FIG. 63 . Similarly, actuator 6258 can rotate actuator shaft 6371 counterclockwise, when viewed from the left, as shown in FIGS. 63-64 , when raising lift point 6128 from a bottom center position, as shown in FIG. 63 , to a top center position, as shown in FIG. 64 , and can rotate actuator shaft 6371 clockwise when lowering lift point 6128 from a top center position, as shown in FIG. 64 , to a bottom center position, as shown in FIG. 63 . By the actuators at the front of body 5910 (e.g., actuators 6255 (FIG. 62 ), 6256) operating in an opposite direction from the actuators at the rear of body 5910 (e.g., actuators 6257 (FIG. 62 ), 6258), pick deck 5920 can remain approximately centered when being raised from a lowered position, such as in FIG. 63 , to a raise position, such as in FIG. 64 , and when being lowered vice versa.

In several embodiments, each actuator arm (e.g., 6362, 6372) can have a length between the corresponding actuator shaft (e.g., 6361, 6371) and the corresponding joint (e.g., 6363, 6373) that is selected to be half of a total amount of the vertical lift provided for pick deck 5920. For example, actuator arm 6352 and/or actuator arm 6372 can have a length of 7 inches (17.78 cm), which can allow pick deck 5920 to be lifted 14 inches (35.56 cm) from the fully lowered position, as shown in FIG. 63 , to the fully raised position, as shown in FIG. 64 . In other embodiments, another suitable length can be used. In many embodiments, each rod (e.g., 6364, 6374) can have a length that is longer than each actuator arm (e.g., 6362, 6372).

In a number of embodiments, each actuator (e.g., 6255 (FIG. 62 ), 6256, 6257 (FIG. 62 ), 6258) can operate concurrently in an synchronous manner such that the top plane of pick deck 5920 remains approximately parallel with frame pieces 6011 and 6012 (FIGS. 60, 62 ) of body 5910 when raising and/or lowering pick deck 5920, such that the entirety of pick deck 5920 is raised and/or lowered when a vertical position of pick deck 5920 is adjusted. In the same or other embodiments, each actuator (e.g., 6255 (FIG. 62 ), 6256, 6257 (FIG. 62 ), 6258) can operate independently of each other. For example, a frontward portion of pick deck 5920 can be raised more than a rearward portion of pick deck 5920 (such as by actuators 6255 (FIG. 62 ) and 6256 being rotated more from the bottom center position than actuators 6257 (FIG. 62 ), 6258), and/or vice versa, which can adjust a pitch position of pick deck 5920. As another example, a left side portion of pick deck 5920 can be raised more than a right side portion of pick deck 5920 (such as by actuators 6256 and 6258 being rotated more from the bottom center position than actuators 6255 (FIG. 62 ) and 6257 (FIG. 62 )), and/or vice versa, which can adjust a roll position of pick deck 5920. In many embodiments, adjustments to the vertical position of pick deck 5920, the pitch position of pick deck 5920, and/or the roll position of 5920 can be made concurrently. For example, a frontward, right side portion of pick deck 5920 can be lowered by controlling the rotation of each actuator (e.g., 6255 (FIG. 62 ), 6256, 6257 (FIG. 62 ), 6258) accordingly.

Turning ahead in the drawings, FIG. 65 illustrates a left side view of harvesting vehicle 5900 traveling through rows of plant beds 5980 when pick deck 5920 is in a fully lowered position. FIG. 66 illustrates a left side view of harvesting vehicle 5900 traveling through rows of plant beds 5980 when pick deck 5920 is in a fully raised position. In many embodiments, as shown in FIGS. 65-66 , harvesting vehicle 5900 can include an arm 6540. In a number of embodiments, arm 6540 can be coupled to both body 5910 and pick deck 5920. In several embodiments, arm 6540 can rotate with respect to body 5910 and/or pick deck 5920 as pick deck 5920 is lowered, as shown in FIG. 65 , and/or raised, as shown in FIG. 66 . In various embodiments, arm 6540 can guide the position of pick deck 5920 to prevent lateral (e.g., side-to-side) movement of pick deck 5920 and/or to prevent yaw movement (e.g., twisting) of pick deck 5920, as described below in greater detail. When pick deck 5920 is in a fully lowered position, as shown in FIG. 65 , pick deck can be at a distance 6591 below the deck of body 5910. When pick deck 5920 is in a fully raised position, as shown in FIG. 66 , pick deck can be at a distance 6691 below the deck of body 5910.

In many embodiments, as described above, pick deck 5920 of harvesting vehicle 5900 can carry one or more robots (not shown in FIGS. 65-66 ), such as harvesting robot 100 (FIG. 1 ), harvesting robot 2000 (FIG. 20 ), harvesting robots 3461-3464 (FIGS. 34-36 ), robots 3804-3807 (FIG. 38 ), and/or other suitable robotic systems, such as the hole-punching robot described above. In many embodiments, each robot can determine a height of the robot from the plant bed (e.g., plant beds in rows of plant beds 5980), such as by using imaging sensors (e.g., imaging sensors 1290-1291 (FIGS. 12-13 ) and/or images sensors 2190-2191 (FIG. 21 )) on the robots. For example, the imaging sensors can determine that the robot (not shown in FIGS. 65-66 ) carried by pick deck 5920 is at a height 6590 (or in some embodiments, at least a minimum height) above the plant bed, when pick deck 5920 is at a lowered position, as shown in FIG. 65 . Similarly, the imaging sensors can determine that the robot (not shown in FIGS. 65-66 ) carried by pick deck 5920 is at a height 6690 (or in some embodiments, at least a minimum height) above the plant bed, when pick deck 5920 is at a raised position, as shown in FIG. 66 . In many embodiments, the height of the robot from the plant bed can be the height of the bottom of pick deck 5920 above the plant bed. In some embodiments, the height information can be determined by the robot based on the imaging sensors determining the distance from the imaging sensors to the crops to be picked. In other embodiments, the height information can be determined by the robot based on the distance from the imaging sensors to the plant bed. This height information can be provided to suspension control system 5803 (FIG. 58 ). In many embodiments, more than one robot can be carried by pick deck 5920 of harvesting vehicle 5900 can provide height information to suspension control system 5803 (FIG. 58 ). For example, in some embodiments, each robot can provide height information to suspension control system 5803 (FIG. 58 ). In the same or other embodiments, the height information can be provided by one or more sensors (not shown in FIGS. 65-66 ) attached directly to pick deck 5920 (as opposed to on the robots). For example, a laser sensor can be attached pick deck 5920, such as at each corner of pick deck 5920, and these one or more laser sensors can determine the distance from bottom of pick deck 5920 to the plant beds. In other embodiments, one or more imaging sensor can be attached to pick deck 5920, other than on the robots. In still other embodiments, other suitable sensors can be attached to pick deck 5920 and used to determine distance information.

In many embodiments, suspension control system 5803 (FIG. 58 ) can receive the height information from the robots, and/or receive attitude information from IMU 6021 (FIGS. 60-61 ), to determine how to control actuators 6255-6258 (FIG. 62 ) to adjust the vertical position, the pitch position, and/or the roll position of pick deck 5920. In a number of embodiments, the adjustment of the vertical position, the pitch position, and/or the roll position of pick deck 5920 can be based on the height information of one or more robots close to the one or more corners of pick deck 5920. In other embodiments, the adjustment of the vertical position, the pitch position, and/or the roll position of pick deck 5920 can be based on an average of height information from all of the robots. In the same or other embodiments, the adjustment of the actuators (e.g., 6255-6258 (FIG. 62 )) can be the same for each actuator (e.g., 6255-6258 (FIG. 62 )) based on the height information received from the one or more robots. In other embodiments, the adjustment of the actuators (e.g., 6255-6258 (FIG. 62 )) can be different from each other some or all of the actuators (e.g., 6255-6258 (FIG. 62 )) based on the height information received from the one or more robots and/or attitude information received from IMU 6021 (FIGS. 60-61 ).

In some embodiments, the height information can be received from the robots, and/or the attitude information can be received from IMU 6021 (FIGS. 60-61 ), regularly, such as on a cycle, and suspension control system 5803 (FIG. 58 ) can provide adjustment control for the actuators (e.g., 6255-6258 (FIG. 62 )) regularly based on updated information received each cycle and/or over a period of cycles. For example, the height information can be sent from the robots, and/or the attitude information can be sent from IMU 6021 (FIGS. 60-61 ), to suspension control system 5803 (FIG. 58 ) on a 1 Hz cycle, a 2 Hz cycle, a 4 Hz cycle, or another suitable cycle.

In a number of embodiments, harvesting vehicle 5900 can operate in an open field subject to weather. The fields can be leveled and setup initially to relatively tight specifications upon initiation, but due to this weather exposure, various areas of the field can be subject to settling or washout due to water and/or wind erosion. To deal with this issue and keep the robots within desired inspection distances for picking speed considerations, harvesting vehicle 5900 can be equipped in several embodiments with suspension control system 5803 (FIG. 58 ) to maintain a height of pick deck 5920, and/or the robots carried thereby, above the plant beds.

In many embodiments, the adjustment of the vertical position, the pitch position, and/or the roll position of pick deck 5920, as controlled by suspension control system 5803 (FIG. 58 ), can beneficially keep the robots from crashing into the plant beds as they are carried by harvesting vehicle 5900. For example, if one or more of the wheels (e.g., 5901-5902) of harvesting vehicle 5900 start to dip into a washed out area, suspension control system 5803 (FIG. 58 ) can detect the lowering of the height information from one or more of the robots, and/or can detect a change in attitude of IMU 6021 (FIGS. 60-61 ), and can adjust one or more of the actuators (e.g., 6255-6258 (FIG. 62 )) to compensate and level pick deck 5920 and/or to keep the robots with a distance range from the plant beds.

In some embodiments, for example, a bottom most part of each of the robots (e.g., picking systems), excluding the gripper in the picking position that is being lowered to pick the crop, can be kept at a certain distance (or within a certain distance range) above the plant bed. For example, the distance can be 2.0 inches (5.08 cm) to 5.0 inches (12.7 cm). In other embodiments, the distance can be another suitable distance. In a number of embodiments, suspension control system 5803 (FIG. 58 ) can adjust the vertical position, the pitch position, and/or the roll position of pick deck 5920 to keep the bottommost part of the robot from the plant bed when the robot is moving with respect to the plant bed and/or when the robot is being held stationary with respect to the plant bed by the RPC (e.g., 6240, 6250, 6260, 6270 (FIGS. 62 )).

Turning ahead in the drawings, FIG. 67 illustrates a top, rear, left side perspective view of arm 6540, a portion of pick deck 5920, and a portion body 5910 when pick deck 5920 is in a partially raised position. FIG. 68 illustrates a top view of a portion of arm 6540 and a portion of pick deck 5920, showing the connection of arm 6540 to pick deck 5920, with the lifting elements removed. FIG. 69 illustrates a top, front, right side view of a portion of arm 6540 and a portion of pick deck 5920, showing the connection of arm 6540 to pick deck 5920. As shown in FIG. 67 , body 5910 can include a mount post 6715 on the left side of body 5910 and/or a mount post 6716 on the right side of body 5910. In many embodiments, mount posts 6715-6716 can be located frontward on body 5910 of the front-most end of pick deck 5920. In several embodiments mount posts 6715-6716 can extend below the deck of body 5910. In many embodiments, arm 6540 can include mounting struts 6741-6742. Mounting struts 6741-6742 can be located at a front-most end of arm 6540. In many embodiments, mounting struts 6741-6742 can extend below the front-most end of arm 6540 to attach to mount posts 6715-6716, respectively, at mount pivots 6742 and 6744, respectively.

As shown in FIGS. 67-69 , in many embodiments, arm 6540 can extend rearward from mounting struts 6741-6742 to attach at an orientate pivot 6740 to pick deck 5920, such as at cross frame piece 6031 (FIGS. 68-69 ) of pick deck 5920. In a number of embodiments, orientate pivot 6740 can attach arm 6540 to pick deck 5920 in a manner that allows arm 6540 to pivot along a side-to-side axis and/or along a front-to-rear axis. In several embodiments, orientate pivot 6740 can include a pivot channel 6735, a pivot component 6749, arm pivots 6745 and 6845 (FIGS. 69-69 ), and a roll pivot 6736. Pivot channel 6735 can be fixedly attached to cross frame piece 6031. In many embodiments, the rearmost end of arm 6540 can be rotatably attached to a pivot component 6749. In a number of embodiments, arm 6540 can be attached to pivot component 6749 at arm pivots 6745 and 6845 (FIGS. 68-69 ), which can allow for rotation of arm 6540 with respect to pick deck 5920 along a side-to-side axis. In various embodiments, pivot component 6749 can be rotatably attached to pivot channel 6735. In many embodiments, pivot component 6749 can be attached to pivot channel 6735 at roll pivot 6736, which can allow for rotation of arm 6540 with respect to pick deck 5920 along an end-to-end (e.g., front-to-rear) axis. In many embodiments, orientate pivot 6740 can allow for pick deck 5920 to roll and/or pitch with respect to body 5910 (FIG. 67 ). In many embodiments, pivot component 6749 can be positioned in pivot channel 6735 to allow pivot component 6749 to rotate around roll pivot 6736 to a limited extent, such as with an angular rotation of no more than 1 degree, 2 degrees, 3 degrees, 4 degrees, 5 degrees, 6 degrees, 7 degrees, 8 degrees, 9, degrees, or 10 degrees, or another suitable angular rotation, in each direction from a center, level position.

In several embodiments, arm 6540 can include a left frame piece 6841 (FIGS. 68-69 ) and/or a right frame piece 6842 (FIGS. 68-69 ). In many embodiments, left frame piece 6841 (FIGS. 68-69 ) can extend from arm mounting strut 6741 at the front-most end of arm 6540 to arm pivot 6745 at the rear-most end of arm 6540, and/or right frame piece 6842 (FIGS. 68-69 ) can extend from arm mounting strut 6743 at the front-most end of arm 6540 to arm pivot 6845 (FIGS. 68-69 ) at the rear-most end of arm 6540. In a number of embodiments, left frame piece 6841 (FIGS. 68-69 ) and right frame piece 6842 (FIGS. 68-69 ) of arm 6540 can form an “A” frame, such that left frame piece 6841 (FIGS. 68-69 ) and right frame piece 6842 (FIGS. 68-69 ) are a greater distance from each other at a front end of arm 6540 than at the rear end of arm 6540. In several embodiments, arm 6540 can include one or more cross support pieces, such as cross support pieces 6843 (FIGS. 68-69 ) and/or 6844 (FIG. 68 ), which can provide structural support for arm 6540 between left frame piece 6841 (FIGS. 68-69 ) and right frame piece 6842 (FIGS. 68-69 ).

In many embodiments, arm 6540 can be connected to pick deck 5920 with one or more stabilizer arms, such as a left stabilizer arm 6746 and/or a right stabilizer arm 6846 (FIGS. 68-69 ). In several embodiments, left stabilizer arm 6746 can attach to arm 6540 at a joint 6747 (FIGS. 67-68 ), and/or left stabilizer arm 6746 can attach to cross frame piece 6031 (FIGS. 68-69 ) of pick deck 5920 at a joint 6748. In a number of embodiments, right stabilizer arm 6846 (FIGS. 68-69 ) can attach to arm 6540 at a joint 6847 (FIG. 68 ), and/or right stabilizer arm 6846 (FIGS. 68-69 ) can attach to cross frame piece 6031 (FIGS. 68-69 ) of pick deck 5920 at a joint 6848 (FIGS. 68-69 ). In some embodiments, joints 6747 (FIGS. 67-68 ), 6748, 6848 (FIGS. 68-69 ), and/or 6848 (FIGS. 68-69 ) can be ball joints, which can allow some flexibility for pitch and/or roll of pick deck 5920. In many embodiments, the stabilizer arms (e.g., 6746, 6846 (FIGS. 68-69 )) can prevent pick deck 6920 from yaw movement (e.g., twisting).

As shown in FIG. 68-69 , in several embodiments, pick deck can include frame pieces 6833-6834. In a number of embodiments, frame pieces 6833-6834 can fixedly connect two separate points on each side of cross frame piece 6032 to cross frame piece 6031 at the location of orientate pivot 6740. In various embodiments, frame pieces 6833-6834 can provide additional structural support for pick deck 5920 as it is guided by arm 6540 and/or support by the lifting elements, as shown in FIGS. 62-64 and 67 .

In many embodiments, mount pivots 6742-6743 (FIG. 67 ) can be located at a position that is approximately vertically equivalent to a midpoint between the position of orientate pivot 6740 when pick deck 5920 is fully raised (as shown in FIGS. 64 and 66 ) and when pick deck 5920 is fully lowered (as shown in FIGS. 63 and 65 ). For example, if orientate pivot 6740 is located just under the bottom of the deck of body 5910 (FIG. 67 ) when pick deck 5920 is fully raised, and orientate pivot 6740 is located 14 inches (35.56 cm) lower when pick deck 5920 is fully lowered, then mount pivots 6742-6743 (FIG. 67 ) can be located 7 inches (17.78 cm) below the bottom of the deck of body 5910 (FIG. 67 ). In several embodiments, the position of mount pivots 6742-6743 (FIG. 67 ) at the midpoint of the vertical position of orientate pivot 6740 can position arm 6540 such that as arm 6540 rotates around mount pivots 6742-6743 (FIG. 67 ) when pick deck 5920 is raised and/or lowered, orientate pivot 6740 at the rear-most end of arm 6540 follows an arc centered around mount pivots 6742-6743 (FIG. 67 ). In this arc, orientate pivot 6740 is located at a front-most position when pick deck 5920 is fully raised and when pick deck 5920 is fully lowered, and orientate pivot 6740 is located at a rear-most position when pick deck 5920 is half-way lowered, such that the orientate is at a midpoint between the fully raised and fully lowered positions. The length of arm 6540 can be significantly larger than the distance of maximum vertical adjustment between the fully raised position and the fully lowered position, such that the front-to-back displacement of orientate pivot 6740 and pick deck 5920 between the fully raised and fully lowered positions, at a front-most position, and the midpoint position, at a rear-most position, is relatively small. For example, when arm 6540 is approximately 10 feet (2.44 m), the front-to-back displacement can be less than 0.25 inch (0.635 cm). In other examples, arm 6540 can be another suitable length that is longer or shorter than 10 feet (2.44 m).

In many embodiments, arm 6540 can advantageously prevent pick deck 5920 from swaying (e.g., side-to-side or end-to-end) during movement of harvester vehicle 5900 (FIG. 59 ), adjustment of pick deck 5920, movement of RPCs 6140, 6150, 6160, 6170 within pick deck 5920, and/or movement of the robots (e.g., picking systems) within pick deck 5920. In several embodiments, by adjusting the vertical position, pitch position, and/or roll position of pick deck 5920, the vertical position of the robots with respect to the plants and/or plant beds can beneficially be adjusted. In many embodiments, pick deck 5920 can weigh significantly less than the weight of harvesting vehicle 5900 (FIG. 59 ) in its entirety, such that the adjustment of the robot positions using the actuators (e.g., 6255-6258 (FIG. 62 )) can advantageously be effectuated by raising, lowering, or otherwise adjusting significantly less weight than when adjusting the vertical position of the wheels.
